It was raining heavy in New York, with the water splashing all over the road, the parked cars, and into the sewer through an open manhole cover, as a car sped over a puddle near it. As the rain water dripped into the sewers, everything in them seemed to be quiet, that was until two rats heard a loud noise from the other side of a wall they were near. They moved just as one of the metal things that destroyed the turtles lair popped out through the wall.
Donatello: It may not look like much...
The metal thing jumps into the sewer and began chasing after the rats.
Donatello: ..but this tin-toy can chomp his way through steel and concrete like Michelangelo through a pizza.
All six turtles all ran down a tunnel in the sewers, as they were chasing after it.
Donatello: A bunch of these Mouser robots saw fit to trash our old lair. They nearly turned our sensei into robo-chow.
They all come into a four-way tunnel system and look around, not knowing which way to go.
"Aghhh!" a voice screamed.
The six of 'em turned down one of the tunnels, and then Don - who was closet to it - pointed at it, as it was the direction it came from.
Six Mousers had a red-haired woman in brown cargo-pants and a purple short shirt - which showed her midriff - trapped against a boarded up tunnel entrance.
Donatello: I look at these incredible machines, and the techno geek in me can't help thinking 'awesome'.
One of the Mousers then turned to the six turtles, who then jumped out of the shadows with their weapons.
Donatello: But the ninja in me can't help but thinking 'payback'!
The remaining Mousers turned to them, and then one began snapping its dentures at them.
Inside their new lair, Mikey was setting up a bunch of TV's, all different sizes and shapes, Splinter was sewing up a practice dummy while sitting on a couch, Elisa came out of one of the rooms with a duster - haven dusted the place - Donnie was holding a blowtorch against a pipe on the upper level - being held by an attachment to a rope, and had a pair of safety goggles over his eyes.
"What's the matter, Mikey?" he asked, before raising the goggles above his eyes. "Can't decide what to watch?"
He turned the blowtorch off and then lowered himself down to the ground.
"I need more pow-e-er captain." Mikey joked, bending down near two plugs. "The Turtle Cave must be set for maximum entertainment potential."
He then connected the wires, which caused a building above them to lose its power for about ten seconds. He picked up the TV remote and then pressed a button on it to turn it on, but loud feedback came out it the screens, making him turn it off again.
"Aw!" he moaned.
"Turtle Cave?" Donnie questioned approaching him. "That is so lame."
"Yeah. I've heard better stuff than that." Elisa shrugged, showing up beside him.
"What would you guys call our new digs?" Mikey asked. "The Shelter."
Donnie and Elisa both thought for a minute.
"How 'bout 'the Sewer of Solitude.'" Donnie suggested.
Mikey turned to them.
"Or the Ninjutsu academy?" Elisa suggested.
"Terrapin Station!" Mikey argued.
"The school for gifted reptiles?" Donnie argued.
"The hidden mutant lair." Elisa argued.
"The hall of Nin-justice." Mikey argued.
Splinter stopped sewing the practice dummy and looked at them while clearing his throat. All three of them turned to him as he got up from the couch.
"We will call this place...home." he told them.
"Hmm...catchy." Mikey grinned.
Donnie and Elisa nodded in agreement.
"Now, what is keeping Leonardo, Raphael and Catharina?" Splinter asked.
Donnie ran over a small bridge - which was over the small opening to the river - while Mikey picked up a set of pipes, as Elisa picked up a small wooden chair.
"They just went to get the last of our stuff from the old lair." Mikey explained.
Don approached his new workshop bench, which had some parts from some of the metal things that had trashed their old place. "And the way the new Sewer Slider is preforming, they should be back any minute now." he explained, as Mikey walked past him while he picked up one of the legs.
He put a screwdriver to it and turned it, but it shorted-circuited, making his eyes widen.
Back in the old lair, Leo picked up the broken canister of ooze which had turned them all into what they were today and walked back towards the Sewer Slider, while Cath put in the last of her medical books.
"Our home for fifteen years..." Leo sighed, putting the canister with the other stuff, and then tied it up. "..and this is all that's left."
"I'm gonna miss this place a lot." Cath cried, small tears coming from her eyes.
"We are all." Leo assured softly, pulling her in for a hug.
Raph walked over to one of the cracked walls. "When I found out who built those home wrecking robo-roaches!" he swore.
He then punched the wall, causing it to crack severally, and caused the room to shake.
"Raph, come on." Leo said, turning to him. "Let's not trash this place more than it already is."
He and Cath then hopped into the Sewer Slider, and then Raph jumped into the drivers seat. He powered it up as a light came on from the front of it, then he and Cath fastened their seat belts up - Leo sitting on top of a surfboard which among their stuff - and then Raph drove off down the tunnel. The Sewer Slider's wheels then lifted themselves up, and then it hovered above the ground as it kept on going down the tunnel.
"Now, remember Raph, Don and I haven't had time to calibrate the accelerator yet." Cath reminded. "So take it nice and..."
Raph ignored her and pulled on the accelerator, speeding the Sewer Slider up.
"..slow!" Cath yelped.
Raph drove further down the tunnel, cheering as he did while Leo struggled to keep himself balanced.
"Whoa!" Leo yelped, as the speed caused the Sewer Slider to go around in a sideways loop.
"What part of going slow didn't you get, Raphael!" Cath exclaimed.
"Ah, come on. I'd call this a successful field test, wouldn't you guys?" Raph asked.
Cath and Leo both realised he was right in a way, and then they all cheered as Raph drove on.
In the new lair, Don was looking at one of the metal things heads on his workbench, when Splinter and Elisa came up behind him.
"Even through it is inactive, that thing still makes me uneasy, Donatello." Splinter told his son.
"This is state of the art robotics, sensei. Brilliant work." Donnie complemented, picking up the head. "I just gotta know what makes it tick."
"Why don't you wait till Cathy returns, and then try again." Elisa suggested. "You always find out better when you both work together."
"Good idea." Don agreed.
Just as he said that, a big light shined into the room, and they all turned to see the Sewer Slider come in. Raph then stopped driving it, then the wheels leveled off, before Raph set it down on the ground.
Leo then hopped of it holding a box. "Hey, good news, Mikey. You're DVD collection survived." he called, spinning it on his finger like a basketball.
He then toss it to Mikey, who then caught it with one hand, the TV remote in the other. "Awesome! Let's throw in something light on story and heavy on gory, 'cause the video monument is ready to rock-and-roll." he grinned.
He turned the TVs on - except two as they stayed blank - which showed a live news report of a building called StockTronics.
"In a press conference today at StockTronics Incorporated, New York's new leading techonloy frim..." came the news reporter.
"Boring!" Mikey yawned.
He was about to change the channel, when Don stopped him.
"Wait!" he called. "I want to see this."
The screens the showed a big room with a few people in - a cameraman, and African-American man with glasses, and a woman with red hair, as Leo, Cath and Elisa approached them.
"Founder and CEO, Doctor Baxter Stockman was on hand to unveil his latest innovation."
"A wise man once said..." Stockman said, taking his glasses off and then cleaned them. "..'build a better mousetrap, and the world will lead a path to your door'." He put his glasses back on and then smiled at the camera. "I say, let the path beating begin.
(The lab)
"For I, Dr. Baxter Stockman, have designed the solution to the city's ever growing rat problem." he explained, pointing to something that was covered up behind him. "Ladies and gentlemen, I give you..."
(The lair)
The four turtles yelped and he pulled back the cover over the object, which was one of the metal things that had destroyed their old home, as Donnie came up behind them with broken one's head.
"..the ultimate expression of rodent termination technology; the StockTronics Mouser." Stockman announced, as the Mouser raised its head.
"Huh?!" Don, Mikey and Cath gasped, as Raph and Splinter approached them.
Don put his hand to his chin for a minute. "I can't believe that the famous Baxter Stockman would try to pass off these killer robots as a good thing." he admitted, holding up the Mouser's head.
"You never know. He may be smart on the outside, but on the inside, he could be horrible or something." Cath deduced.
Mikey took the Mouser head of Donnie. "And what's up with those glasses?" he asked jokingly, before putting it into his hand like a puppet and mimicked Stockman. "Nerd city."
Cath rolled her eyes in annoyance, as Raph ran at the TV's, and then smashed one of the smaller ones with one of his Sai's by stabbing it.
"I say we head over to StockTronics and kick some serious shell." he snarled.
He turned left and began to run off while twirling his Sais, when Splinter cut him off.
"Absolutely not!" he scolded, whacking Raph on the head with his walking stick. "Your last venture to the surface was a disaster." he explained, recalling the armoured car incident. "You can ill-afford to be seen by more humans."
The remaining TVs then showed the red-haired woman, who was shying away from the camera while holding a cardboard box.
"My lab assistant, Miss April O'Neil, will release several rats into the simulation chamber." Stockman explained.
April then approached it, which was shaped like a small maze.
"April..."
(The lab)
"..proceed, my dear." Stockman instructed.
April tipped the box over, and about a dozen rats fell into the maze, and began looking around. As one peeked over the maze, Stockman picked up the Mouser, and put it down by the maze entrance, and then activated it.
"Now observe the sheer genius of my Mouser in action?" he asked, as the Mouser began to run through the maze.
The Mouser turned its head left to a open gap in the maze, as a rat turned right on the other side at exactly the same time. The rat then squeaked panickily, and then turned and ran off as the Mouser began to give chase to it.
(The lair)
The Turtles gasped at what they were seeing, as the Mouser caught the rat and then gobbled it up
"Whoa, man. I'd sure hate to be a rat in this town." Mikey admitted, before remember Splinter was a rat. "Huh? Oh, sorry, sensei."
"Well, you have to admit, if those Mousers here to get rid of rats in the sewers, that might be why they trashed our old lair." Elisa admitted.
"You've got a point there, sis." Cath agreed, before they both turned to their father. "No offence, sensei."
"None taken, my daughters." Splinter said, understanding what they meant.
"Still no excuse for wrecking the place." Raph snarled.
In the lab later that day, Stockman and April were both watching a recording of the news report.
"And the Mousers search and retrieval functions are all ingeniously controlled by a remote mother computer." the Stockman on TV said.
April then touched her TV self. "Oh, this is so great." she said happily, before turning to Stockman, who was behind her. "My friends, my family will finally see I really do work with the Baxter Stockman."
Stockman grinned while folding his arms. "You flatter me, Miss O'Neil." he said proudly, before turning his head away from her. "I like that."
April then put up something up on the computer which surprised her. "Oh." she gasped quietly. "That's strange."
Stockman turned back and looked at the computer screens, which showed the Mouser prototypes, but about a third were missing.
"I was running a routine diagnostic check." April explained. "Half the Mouser prototypes ain't even transmitting. It's like they just vanished."
"I'm sure it's nothing, April." Stockman assured, strutting slightly as April checked on the computer. "Probably just a computer glitch. I'll have the systems tech go over it in the morning."
"But what if the Mousers have been tampered with?" April questioned. "We should go over all their transmission backups."
Stockman touched her shoulder, getting her attention. "That won't be ness, April." he assured sternly, before he turned around. "Now, if you'll excuse me..." he turned and walked towards a black door. "..I'm excepting an important call from a from a very significant financial benefactor."
The door opened up automatically, and then closed again once he walked inside, as April put her hand on her chin, getting spurious of her boss.
In the lair, the Turtles all had their weapons out and had surrounded Master Splinter, as they were now doing a training session, with himself ready for his children's attacks.
Donnie went first, spinning his Bo Staff around and then jumped at Splinter. He tried to hit him with his Bo, but Splinter blocked it with his walking stick, and then spun around as Donnie fell to his knees. He then tried to hit Splinter again, but he blocked it, then he spun around and whacked his son in the shell, knocking him away as he tried to get back up.
"Uh!" he groaned, turning to his sensei.
"Do not lea with your shoulders, Donatello." Splinter advised.
Cath then charged in while spinning one of her Tonfas, which she then tried to whack Splinter with, only to miss. He then spun around to hit her with his stick, but she blocked it with her other Tonfa, but then he whacked her in the chest, as she spun around to hit him with her other one, knocking her to her knees.
"Never underestimate your opponent, Catharina." Splinter told her.
Leo then jumped out from behind Splinter while raising both his katanas above his head.
"Hyah!" he shouted.
Splinter then turned around and whacked him with his walking stick, sending him flying back further than were he was standing, landing and sliding on the back of his shell.
"Faster on your counterattack, Leonardo." Splinter said.
Mikey then charged at him, and then tried to hit him with one of his Nunchucks, but Splinter ducked and then tripped him up with his walking stick, knocking him down.
"Mind your foot work, Michelangelo." he said.
Elisa then charged in at Splinter with anger in her eyes, and tried to slice him with one of her Kamas, but he dodged it. He then spun around whacked her in the back of the shell, knocking her into a pillar, making her slightly dizzy.
"Do not charge into a battle blindly, Elisabetta." Splinter advised sternly.
Raph then charged at him with even more anger than her. He then tried to stab him with one of his Sai's, but missed as he jumped over him. Raph then turned around and threw one of his Sai's at Splinter, but he knocked it aside with his walking stick. He then knocked the other Sai out of Raph's hand, and then hit him in the chest with his stick, pinning him against a pillar.
"You are distracted, Raphael." he realised. "You must learn to focus your attacks."
He let his son go, who then rubbed some dust off his shoulder.
"I'd like to focus my attacks on that Stockman guy." he said, gritting his teeth lightly.
Splinter then walked away, as Raph ran past him.
"Why can't we just go topside and go show 'im a little mean-in-green?" Raph asked hopefully, stopping in front of Splinter.
"Because I forbid it!" his father said sternly.
"Ah!" Raph groaned moping.
Splinter then walked past him to one of the doors Donnie had built - which was made of green glass - as the other Turtles gathered around Raph, putting their weapons away as they did.
"We will resume your training in the morning." their father told them, as the doors opened automatically.
He then walked inside his room, and then the doors closed behind him.
"Ha. 'We will resume your training in the morning.'" Mikey mimicked.
"I heard that!" Splinter called from his room.
"Busted!" Donnie laughed, embarrassing Mikey.
The girls both giggled.
"Ah, I'd like to bust a few heads!" Raph snarled, turning to his siblings - punching his fist as he did.
"Chill, bro. We don't need no stinking surface world." Mikey assured, as he walked towards the coach, before jumping onto it. "We got late movies, top 10 video countdown..." he picked up the remote and turned on the TVs. "..BMX third highlights..."
Donnie walked towards his lab bench as Mikey went on, changing the channels as he did.
"..some really weird Korean language soap opera." Mikey finished, as Donnie put his goggles on.
"Or, you guys could give me a hand with these Mouser parts." he said, as he turned on a blowtorch.
He then held it against one of the Mouser's legs.
"If I can get one working, we can trace them back to its source and find out what Stockman's really using them for." he explained.
Cath put her hand to her chin. "That's not a bad idea, bro." she grinned, before jumping over to him. "I'll assist you."
"Thanks, Cath." Donnie said, as Cath put her goggles on.
Raph then faked a yawn as Leo and Elisa both watched him.
"Nah, I'm beat." he yawned, before walking off. "I'm gonna rack."
Leo and Elisa turned to each other.
"Since when does Raph turn in so early?" Leo wondered.
"You got me." Elisa shrugged, not knowing herself.
At StockTronics, Stockman was behind his desk in his office, speaking to his so-called client in on a video phone.
"The Mousers will be ready, when I decide they're ready." he told the client again. "Our first field test was..."
"Was a complete failure!" his client snapped, lurking in the shadows. "I do not tolerate failure!"
"Which is why you'd make a lousy scientist." Stockman argued. "The test was suppose to expose any possible design flaws. As a result, I've already upgraded the Mousers for greater durability..."
Outside his office, April had her ear pressed against the door, wanting to know what was going on.
"..and I assure you, they'll preform flawlessly for the next stage of the plan."
"They had better, Dr. Stockman, for your sake!" the client threated.
April gasped at the client's words.
Back in the lair, Mikey had fallen asleep on the coach while watching the TV, and was snoring loudly, as Elisa was meditating, trying to clam herself down from the training exercise, while Cath and Donnie were still working on the Mouser.
Unknown to any of them, Raph came out of his room quietly, and then jumped down to the ground floor, landing on his tiptoes near the bridge. He then ran towards the lair entrance, determined to sneak away to StockTronics unnoticed. Once inside the tunnel past the entrance through, he saw Leo standing right in front of him, with his hands on his hips.
"Midnight stroll?" Leo guess sarcastically, as Raph stopped.
"Out of my way, Leo?" Raph asked demandingly.
"Master Splinter say 'we stay put'." Leo said sternly.
"Look, I'll go through you if I have to!" Raph warned, getting ready to fight.
"I'd like to see you try, hothead!" Leo retorted, getting ready to fight as well.
"Careful what you wish for, Splinter Jr." Raph advised, before tackling his brother to the ground like a wrestler.
They both then tossed and turned as they grappled each other, but then stopped when they saw a Mouser run past them.
"Hey, guys, we got one working!" Donnie called, referring to him and Cath, as they - along with Mikey and Elisa - all ran towards them.
"Come on. He's faster than he looks!" Mikey explained.
The four of them then chased the Mouser out of their home and into the tunnels, as Raph turned to Leo.
"So, you're just gonna let that Mouser roam free?" he asked.
"Master Splinter is so going to kill us." Leo mumbled, before getting off Raph.
He then ran to the tunnel entrance, before stopping and turning to Raph.
"Well, you coming or what?" he asked rhetorically, knowing what the answer was, before running off.
"If you insist." Raph scoffed, before getting up and followed his older brother.
Back at StockTronics, April was working on the computer again, when Stockman came out of his office.
"Goodnight, April dear. Try not to work too late." he cautioned, as she spun her chair around. "You know I don't like to pay overtime."
"Goodnight, Dr. Stockman." April said.
A white door then opened up similar to the office one, and then Stockman walked through it, then he turned to April one last time, before it closed over him.
April then got up from her chair and ran towards the office, and then ran inside it once the door opened. She then ran towards the desk and sat down behind him, before she began to work on the computer.
"Now, let's find out what kind of plan you've been cooking up with those Mousers, Dr. Stockman." she muttered.
As she started hacking the computer to find out the plan, a foot symbol suddenly appeared on the computer - the same one belonging to the ninjas the Turtles battled just days ago.
"I've never seen that icon before." she muttered suspiciously.
She moved the mouse over the icon and then clicked on it, and then she heard a noise.
"Huh?" she muttered, getting up. "What is..."
She then gasped as a bookshelf opened up from both sides, reveling a secret elevator.
Back in the sewers, the Turtles kept chasing the Mouser through the tunnels, and then it began to run over a pipe. One-by-one, they all followed it - first Mikey, then Don, Cath, Elisa, Leo and then Raph. They all kept following it, as a number of heaps of water came out of the tunnels above them, creating a whirlpool beneath them.
"Watch your step here, guys." Leo cautioned. "Don't want to end up as Turtle Soap."
The Mouser then stopped at the end of the pipe, which was by a dead-end wall, but then it began to scale it easily on his feet, surprising all the Turtles as they bumped into each other.
"What the?!" Cath gasped.
"Resourceful little critter!" Donnie moped.
"So what do we do now?" Raph asked.
"Like Master Splinter says; a ninja is always prepared." Leo quoted, pulling out some Shuko Spikes out of his belt.
"I thought that was the Boy Scouts." Mikey joked, as he put his spikes on his hands.
"Very funny." Elisa said sarcastically, unamused.
Back in the office, April approached the elevator slowly, and then entered it. She then pressed a button in it, then the doors closed, and then she gasped as she fell back slightly onto a handlebar, as the elevator began to go downwards very fast.
Back in the sewers, the Turtles were all climbing up the wall after the Mouser, when Mikey groaned and turned to Leo and Elisa below him.
"Ah! Next time, let's leave the wall-crawling to the dude in the blue and red tights." he complained.
"You read way too many comic books!" Leo retorted, annoyed.
The Mouser then came to a large pipe - one that was spitting out a gush of water - and then climbed into it. Mikey was the first turtle to reach the pipe, and then climbed in after the Mouser, followed by Leo, Cath, Don, Elisa, and then Raph.
As they chased after it down the pipe tunnel, Mikey turned to the brains in the family. "Just curious, guys, what's to stop old turbo-jaws from munching up another 6.2 on the Richter scale?" he asked Don and Cathy.
"We shut down it's jaw servos as we rebuilt it." Cath explained.
"It can't even chew through a stick of gum." Donnie assured.
The Mouser then stopped by a bunch a pipes, and then began to munch through them, surprising all the Turtles.
"You were saying?" Raph asked Don and Cath, both speechless.
"But we...we're sure we shut it down." Donnie argued in disbelief.
Mikey walked over to them and touched Don's shoulder, as Raph grinned. "Oh, Don and Cath have finally lost their techno mojo." he joked, putting his hands on his hips. "Sad really. At least Cath still has her doctor mojo."
Cath then whacked him on the head with one of her Tonfas.
"Ow!"
"Not funny, Mike." she scowled, putting her Tonfa away. "What do you think, Don?"
Donnie put his hand onto his chin. "It must have some kind of security override routine." he deduced.
"Of course." Cath agreed, smirking. "That explains why it was able to cut through the pipes. Come on, guys!"
They all then ran closer to the chopped up pipes, when Donnie suddenly stopped and looked at a pipe in front of him.
"Oh no." he murmured, getting the others to stop.
"What is it, Don?" Leo asked.
"If I'm not mistaking, that's a serious water main hanging right over our heads." Don guessed.
"So?" Raph asked confused, as the pipe began to crack.
"So? Guess who just ate through the support pipes?!" Cathy exclaimed, pointing at the chopped pipes.
They all looked up as the pipe cracked some more.
"Incoming!" Leo yelled.
Before they could however, the pipe slit open, and a large gush of water overcame them all. They all screamed as the water carried them all towards the end of the tunnel they had climbed into only minutes ago. They all began to fall towards the whirlpool, while Don pulled out his Bo Staff, and then managed to get it onto a small pipe, with one hand on either side.
"Grab on!" he shouted.
Leo then grabbed hold of his feet, followed by Cath, Elisa, Raph and then Mikey.
"Whoa!" he yelped.
"Ow!" Raph cried, as Mikey accidently dug his Shuko Spikes into his legs. "Watch were you point those Shuko Spikes, Mike."
Mikey began to swing himself and Raph forward. "Ah, keep your shell on, Raph. I got an idea." he explained.
"Mike!" Leo shouted.
"Are you nuts?!" Elisa exclaimed.
"Wait, what are you..?!" Leo questioned.
Mikey then let go of Raph's feet, and fell into a waterfall of sewer water, followed by Raph, Elisa, Cath, Leo and then Don, but managed to land with their Shuko Spikes into a wall on the other side.
"Guys, you okay?" Don asked.
Raph spat some water out of his mouth. "Peachy." he grumbled.
"We are never do that again, Mike!" Elisa scowled at her youngest brother.
Mikey blushed while nodding in agreement.
Back in the elevator, it kept moving downwards, as April kept hold of the handrail for like five minutes or so, until it suddenly stopped, surprising her.
"Oh. Finally." she sighed in relief.
The elevator door then opened up, and she walked into a small hallway with glass on either side of it. She then looked through the glass to see an army of Mousers being made on conveyor belts or being lowered onto platforms by claw cranes, which in her mind, was more than necessary.
"I don't care how bad the city's rodent problem is." she muttered. "This is serious overkill."
She then walked further down the hallway, but unknowingly tripped a silent alarm as she went.
In the sewers, the Turtles were now back in the tunnel where the Mouser had given them the slip by sending that gush of water at them. Raph jumped and grabbed hold of a pipe, and then landed on the ground. Leo, Mikey and Cath then landed behind him, and then so did Donnie and Elisa.
"When I get my hands on that metal-menace, I'm gonna grind him into little bot-burgers!" Raph swore, as he took of his Shuko Spikes.
"Whoa, take it easy, bro." Cath advised, as she and the others took theirs off.
"Yeah, Raph. We've still gotta keep him in one piece." Don explained.
"What makes you think we'll even find the little blender bud?" Mikey wondered.
"Mikey's right there." Elisa agreed. "He gave us the slip when he chewed through those pipes that made that water blow us away."
"I think he left us a few clues." Leo answered, pointing to the hole in the wall and pipes.
In the lab, April was now hacking one of the hidden computers.
"Rat problem, my eye. What are you really up to, Stockman?" she wondered.
"Now, now, Miss. O'Neil, that would be telling." came Stockman's voice.
April turned and saw him walked through another elevator behind her, and then he walked towards her.
"Suffice it to say, my army of Mousers will make me a very rich and powerful man." Stockman said, as a claw crane moved in behind the glass.
"But, ain't you already a very rich and power man?" April questioned, as the glass lowered itself - as Stockman had a remote hiding behind his back.
"Ah, Miss. O'Neil, so brilliant yet so naïve." Stockman complemented, fiddling with his glasses. "I will truly miss working with you."
"What?!" April exclaimed. "You mean I'm fired?!"
"In a manner of speaking." Stockman confirmed, pressing the remote.
"Huh?" April muttered, as the claw crane suddenly moved towards her.
It then grabbed her and lifted her out of the room, and then moved her towards one of the platforms full of Mousers, and then dropped her there - ribbing part of her lab coat off as it did.
"I'm afraid I can't let you live, Miss. O'Neil." Stockman admitted, walking towards the computer. "You've seen far too much already and..." he pressed some buttons on it. "Well, let's just I say, I have trust issues."
April threw off her ripped lab coat, as the Mousers all around her came to life.
In the sewers, the six Turtles came out of another hole the Mouser they were chasing had made, only to now find themselves in the subway tunnels. They all then looked around for the metal menace, when Donnie spotted it on the other side of the tracks.
"There!" he shouted.
They all turned to it, and then began to chase after it. Raph ran on ahead, when Leo and Elisa grabbed him by the shoulders, as they both heard a noise.
"Look out!" Leo shouted.
They pulled him back, just as a subway train ran right past them.
"Next time, look both ways first." Elisa advised sternly.
The minute the train had left, they all saw that the Mouser had disappeared.
"Whoa, Robo Houdini." Mikey said amazed.
"Wrong! Robo hitchhiker." Leo corrected, spotting the Mouser hanging onto the end car with its jaws.
"We'll never catch him now!" Mikey complained, as the train went out of sight.
"Two can play that game." Raph assured.
Elisa smirked, knowing what he had in mind, as they both took their weapons out, liking this idea.
They all then heard another train coming, as once it came towards them, both Raph and Elisa jumped onto the front car, and dug their weapons into it to keep still.
"What a pair of maniacs!" Leo exclaimed.
"Yeah." Don agreed, but they knew Elisa wasn't always like this, unlike Raph.
"Hey, wait for us!" Cath shouted.
They all then jumped onto the top of the train - as it was longer than the first one - Mikey climbing up from the slide gate of one of the cars.
The Mouser then jumped off his train after about another two minutes of riding it, and then ran off. Once the train with the Turtles were on came towards the area, Raph and Elisa spotted a hole in the wall - as the Mouser had chewed through it.
"There's our stop." Raph decided.
They both then jumped off the train, followed by Mikey, Leo, Cath and then Donnie, and then they all walked towards and then through the hole.
In the lab, a worried April saw and then picked up a fire extinguisher, and then aimed it at one of the Mousers.
"Keep back. I know how to use this." she warned.
The Mouser growled, but then she fired some foam out of the extinguisher at it, but it had no effect on it. It then charged at her madly, but then she whacked it on the head with the extinguisher, squashing its head.
"Ha!" she said, putting the extinguisher over her shoulder.
The rest of the Mousers then charged at her. She tried to whack one with the extinguisher, but it grabbed it with its jaws, and then destroyed it, creating a huge smokescreen from the foam. April then ran away worriedly, then turned around and ran along the side of the platform, using the foam to cover her movements, and then managed to make it to a closed door.
"You can run, Miss. O'Neil, but you cannot hide from my Mousers!" Stockman warned through the microphone.
April pulled a lever down beside the door, and then it opened it, leading into the sewers. The foamed smokescreen went through the door, and then April went in and looked around, before falling to her knees into the water. She then quickly got back up and ran off down the tunnel.
She then came into an area with eight different tunnel entrances - including the one she came through.
"Which way out?!" she wondered franticly, as the foam followed her. "Which way out?!"
The foam soon blocked all but one, and then she ran right down it, having made her choice.
Unknown to her, the Mousers started coming through the door, determined to find her.
Meanwhile, the Mouser the Turtles were chasing, was now in another part of the sewer. The Turtles all came through a tunnel, and then Mikey spotted him, when another Mouser came up in front of them all.
"Whoa! Who invited him?" Mikey wondered, pointing to the new Mouser.
"You got me?" Cath shrugged.
"I got it." Raph assured.
He threw a Shuriken Star at the Mouser, which hit and sliced part of its head open, and then it hit the ground. Mikey and Raph then high-threed each other, as the Mouser suddenly got back up.
"This is not good, guys." Leo gulped.
"Way to go, Raph!" Elisa scowled, getting Raph and Mikey to turn to the Mouser.
The Mouser then growled at them, when Donnie spotted a lot more approaching them.
"Neither is that." he said, as the Mousers surrounded them. "These chrome domes are a lot tougher than the last batch."
The Mousers growled at them.
"Yeah." Raph agreed, as the Turtles brought their weapons out. "And there's a lot more of 'em, too."
"Guess Stockman's increased the armour on them or something." Cathy deduced.
"And doubled the amount in at StockTronics." Elisa added.
"Great, just great." Raph muttered sarcastically.
Donnie then yelled while jumping, Raph charged while pointing one of his Sai's down, and Cath spun one of her Tonfas around. Leo jumped with both his swords spread out, Elisa charged while holding one of her Kamas over her head, and Mikey spun both his Nunchucks around.
Raph then stabbed one in the head with his Sai, then Mikey whacked another's head with his Nunchucks, and then Elisa sliced one in half with her Kamas. Leo sliced off another twos heads, then Cath whacked one over the head with her Tonfa.
Don then bent his Bo forward over another's head and pole vaulted away, as Raph stabbed another as it jumped at him, and then threw it away.
Donnie then vaulted past another, destroying it as he went, and then whacked another two away like his Bo was a baseball bat.
Raph then jumped over two more, and then landed on their heads, squashing them.
Elisa sliced off another's head, when another grabbed her by the arm with its dentures. "Cathy, think fast!" she shouted, tossing it to her sister.
Cath whacked one over the head with her Tonfa, and then turned to the one Elisa threw at her, before wracking it by the neck, knocking its head off.
Mikey then wrapped one of his Nunchucks around ones neck as it jumped at him, pulling it to the ground. He then spun his other Nunchuck, and then whacked another away as it jumped at him, sending it flying towards the ceiling.
"These Mousers are incredible." Donnie admitted. "The servo-mechanics, the circuity, the articulation."
Raph stabbed one with both his Sais, before turning to his brainy brother. "Gee, Donnie, why don't you just marry one away?" he told him sarcastically, stabbed another in the neck as he did.
Elisa then sliced off another's head with her Kamas as it jumped at her, and then the head bounced along the ground.
Donnie then kicked another away, while Raph stabbed another two with his Sais, and then Don whacked another away, as Elisa jumped and squashed another with her feet.
About a dozen then approached Leo, and then he sliced off one of their heads with his swords. "Guys, the only way to stop them is to slice their heads off!" he called, while slicing off another's head.
"Well, ain't that great news, for the Turtles with the blades." Mikey retorted sarcastically - knowing Leo, Raph and Elisa would be better at that than the rest - before whacking one over the head with one of his Nunchucks.
"He's right there." Cath agreed, getting what Mikey meant as she whacked one away from her with her Tonfas.
"Drive them this way!" Raph called, as one grabbed hold of one of his Sais, before he tossed it to Elisa. "We'll slice and dice!"
Elisa then sliced the one Raph threw at her in half, and then all six of them gathered together, as more approached them.
Donnie then whacked two away with is Bo, then Cath bashed one over the head with her Tonfas, squashing it, and then Mikey whacked ones head off with his Nunchucks. Raph then stabbed two with his Sais, then Elisa sliced off another's head with her Kamas, and then Leo sliced one in half with his swords.
Cath then whacked one in the neck with her Tonfas, knocking its head off, then Raph stabbed another, then Mikey knocked another's head off with his Nunchucks, then Elisa stabbed one with both her Kamas, and then Leo sliced another in half leaving none but one left.
"Great job, guys." Donnie said, before spotting the one still active. "Just make sure we leave one..."
Raph ignored him and jumped and stabbed the Mouser in the head with both his Sais, and then stomped on its head repeatedly.
"..intact." Donnie finished.
"So much for tracing them back to the source." Leo sighed with sarcasm, putting his swords away.
"After all that work Don and I put in rebuilding that thing, it still lead us nowhere." Cath sighed sadly.
Elsewhere, April was still running through the tunnels away from what was left of the Mousers - the Turtles having destroyed most of them. She briefly looked back, as three Mousers showed up in front of her. She screamed as she turned to them while stopping in her tracks, before she turned around and ran back the way she came, but then stopped when three more showed up on that side.
She backed away slightly, before seeing a tunnel to her left, and then ran down it madly - as it was her only way left - as the Mousers chased her. She ran so fast, she ended up tripped over, and then she turned around while sitting up. She then backed away slowly from the Mousers, only to get trapped by a bunch of boards, blocking off the rest of the tunnel.
She then tried to pulled one off, but then realised it was too heavy for her, and then she screamed, realising she was trapped. The Mousers growled as they moved towards her, and then she screamed while closing her eyes, thinking she was done for.
Before the Mousers could attack, one was knocked away by a Bo Staff, then the second had its head knocked off by a pair of Tonfas, and then the third got stabbed with a Sai. The fourth then had its head knocked off by a Nunchuck, then the fifth was stabbed by a pair of Kamas, while the sixth was sliced in half by a sword.
April covered her eyes with her hands briefly, but then lowered them and opened her eyes, to see the Mousers now nothing but junk. She then looked in front of her, and saw the six Turtles in the shadows, as they put their weapons away. (Cath and Elisa both being between Leo and Raph)
"Oh...Oh, thank you!" April said gratefully, as they approached her. "Thank you so much! You saved my...my..."
"Hey, how're you doing?" Mikey asked, bending forward, coming out of the shadows.
April then fainted at the sight of him, and then he picked up her bridal style, before turning to his siblings.
"Hey, so, can I keep her?" he asked hopefully.
The others stared at him in annoyance.
