Season 1 episode 1 "Birthday surprise"

Four brothers. Four giant mutant, ninja, turtles, but regardless, they were brothers more or less. They sat around a table, celebrating their fifteenth birthday, or rather, mutation-day. Leonardo was the eldest, he often took responsibility for his brothers and wore a blue bandana. To his right was the second oldest, wearing a red bandana, Raphael, who was hot-tempered, but deep down, would do anything for his family. To Leonardo's left was Donatello, the smartest, clad in purple, and the youngest, Michelangelo: a free-spirited 'party dude'. Then, sitting right across from the eldest, was a giant brown mutant rat wearing a maroon robe: Splinter. He acted as their father for the last fifteen years.

They ate old cake Mikey found in the trash. Wasn't the best, but it was the best they could get.

Leonardo put down his fork, pushed his plate away, and started twiddling his thumbs, "Father, now that we're fifteen," he looked down and slumped a bit, "...can we...go...to the surface for a while?" he spat out quickly.

Splinter set down his fork and looked at his son "Why? I already go out and search for everything that we need to survive."

Leo stood up and his brothers watched him "Yes, I understand that, but only you get to see the world. What about us? We want to see too."

"Father, if you don't let us, we'll bug you until you break down," Mikey said with a mischevious grin.

Splinter was about to say something, then Leo went on and on about historical and fictional figures being great leaders, and that if they were let out of the sewers, he'd be that leader.

Donnie put down his fork and said, "Please. I'll build you a new TV with all the new junk I find out there."

"If you don't let us out there, I'll break a lamp," Raph said with a laugh.

Leo continued, "...and George Washington…"

Splinter slammed his hands on the table. "My sons. Please, let me speak. If I let you and your brothers above the surface, promise me that you'll only go out at night, and promise me to be back by ten o'clock."

The turtles looked at each other, then back to their father and nodded. Mikey closed his eyes and fist-pumped and said, "Best birthday present ever!"

An hour later they were packed up and ready to go, just waiting for nightfall. They were all in the living room, Donnie started upgrading their shell-phones in the event of an emergency, Raph punched the punching bag murmuring to himself, and Leo and Mikey sat together reading comics.

Mikey was reading issue forty-five of his beloved Justice force comics, then he went wide-eyed and looked at Leo "Dude, not to spoil it, but someone doesn't survive this issue."

Raph stopped for a moment and looked at Mikey, "It's a comic, what do you expect? So, which villain was it? Hmm?"

Mikey shook his head, "Nuh uh. It was a good guy, thank you very much. It was Ananda."

"Oh, crap. Really?"

"Mmmm hmm."

"Thanks for the spoilers, guys," Leo whined. He turned to look at Donnie. "Are the phones ready?"

Donnie's tongue was sticking out as he screwed in one last screw "Done! Now we can track each other if we happen to get lost!" he said with a big smile, handing the others their phones back.

"Right, that's not creepy at all," Raph said, rolling his eyes when he got his phone back.

"Alright, I'll go let master Splinter know that'd we're ready," Leonardo said as he walked down the abandoned sewer that served as a hallway.

At the very end was Splinter's room, and he peeked inside "Umm, we're going out now," he said pointing down the hall, then walked back into the living room.

"Alright, who's ready," he said with a confident look on his face and his hands on his hips. The others stood wide-eyed and Donatello pointed past Leonardo, making him turn around and go "Huh?"

Splinter walked up to them and came to a stop right in front of Leo, "My son, please stay out of trouble. Stick to the shadows, only interfere when someone absolutely needs help. And that goes for all of you, understood?"

"Hai sensei." they all said it together, then walked out, both excited, and worried.

A young woman - about twenty or so, with long red hair held back in a bun, green-blue eyes, and an outfit consisting of a yellow t-shirt, blue jeans, purple sneakers, and a white lab coat - stood next to an African American man - probably about mid-thirties, with glasses, and wearing a white long-sleeved shirt, black jeans, black sneakers, and a lab coat, similar to his partner.

The two worked together on small robots, called 'mousers', made to hunt down mice and rats.

The woman looked at the man, excited that their product was ready to be shown, "I can't believe I helped you invent such a revolutionary machine." she said with a big grin.

Baxter looked at his assistant and smiled a bit "Well, I don't think I would've come up with this without-" his phone started vibrating in his pocket. He took it out and looked at the caller ID "One minute, I need to take this. April, you can take a break if you'd like." he said, making small swatting motions, trying to give her a hint to leave.

April nodded, said "Later," and walked out.

Soon she left, Baxter answered his phone, said "On it", and turned on a few mousers, some of which hopped out the door, others burrowed.

Splinter sat quietly in his room, meditating when suddenly a crash was heard. He got up and saw a bunch of small robots heading his way. Each mouse that got close enough began attacking, biting away and clawing with their little feet. He smashed mousers left and right until he got to the living room. The couch was more torn up than usual, the TV was smashed, the coffee table was knocked over, but luckily, the phone was still intact.

He picked up the phone and called Leonardo.

It was already 9:07 PM. The four turtles sat atop a building, right across from a bank, waiting for some action. Leo's phone rang. He pulled it out of his belt and answered "Yes? Hello?"

Splinter could be heard panting over the phone "My sons, come quickly," then there was a huge crash, followed by beeping.

Leo turned off the phone "Guys, let's go. Splinter's in trouble."

While Leo, Raph, and Donnie ran right, towards home, while Mikey was in such a hurry he ran left. Raph sighed and ran for Mikey, grabbed the back of his mask, and pulled his younger brother in the direction of the others.

Meanwhile, the alarms in the bank began going off while the Turtles walked off.

April came back from getting dinner. She probably spent about thirty minutes out. As she walked up to the building, there was a blonde girl with ice blue eyes - about seventeen, wearing a navy blue tank top, blue short shorts, and a lab coat, clearly faking being a scientist.

April looked at the girl curiously. She looked at her phone, checking for a new text from Baxter about this new employee. When she looked back up, the girl seemed to have vanished. She tapped her finger on her chin.

She proceeded to walk into the building. Mousers hopped up and down throughout the halls, every once and a while, a crash could be heard. None of them seemed to pay attention to April, but they were certainly bothersome. April passed by Baxter's office and overheard him still on the phone. His back was turned, so she stopped and watched from the doorway.

Baxter sounded uneasy "Y-yes sir. I programmed them to rob the banks for you," he rubbed his forehead, "Yes. April O'Neil is on break. Yes, she has no idea and I plan to 'get rid' of her as soon as possible." April gasped, and Baxter turned around, "Sir, may I be excused for a minute," he hung up the phone and spoke into a small remote "Mousers, attack!"

April screamed and ran outside. Mousers snapped at her, tripping her and making it difficult as she ran through the streets.

The turtles climbed into the sewers, one after one. There was a boarded-up section, where water wouldn't flow. They ran until they got to the center of the abandoned area, this served as their living room. Upon entry, Mikey got close to Donnie and began hugging his arm, crying at the sight of the wreckage, and his voice cracked to the point that he almost sounded like a little kid, "Daddy?"

There was a small smashing noise, followed by a whir. Splinter came out from the kitchen, his kimono was torn up, but it was clear who won.

Leo looked into his father's eyes "W-what happened here?"

Splinter put a hand on Leonardo's shoulder and said: "Come with me." He sat in the middle of the floor and motioned for the Turtles to sit in front of him.

April climbed into the sewers in the hopes that she couldn't be found down there. Before she put the manhole cover back a mouser came up to her. She smashed its head off and ran off. She saw the boarded up area and moved a few boards aside and passed through, in the hopes that she could hide.

Splinter could sense April coming. They saw each other. She fainted. A thud sounded. The turtles turned around.

Mikey screamed.

Donnie looked at her curiously "It's a girl..."

Raph said something under his breath that sounded rather foul.

Leo walked over to her and looked back at Splinter "What should we do?"
