"Let me start at the beginning," A video shows the turtles and Amy dealing with a one-eyed robot with two legs. "I first met the turtles and Amelia in a battle that raged on for hours." Donnie jumps up as his staff turned into a drill. "Since that first battle, I knew—that's not me, I'm over there!" The camera pans over to a small fuchsia skinned mutant worm with pink and purple stripes as well as arms. He has blonde hair brushed upright, yellow-green eyes with red pupils and thick black eyebrows. He also wears a dark blue dress coat with a yellow-green button.
"Prepare to face the awesome wrath of my incredible-" He doesn't get to finish his little monologue as Donnie lands on him.
"I knew that at this first fantastical battle, that we would meet again." While the turtles and Amy are fighting bowling pin mutants at a bowling alley, one of them lands on him. "And again." In daylight, Raph kicks a soccer ball on him, followed by the others. "And again." Warren prepares for a fight right outside Smith's Sweets during closing time, where Amy and the turtles are eating cupcakes made by the brunette herself. They seem to be enjoying them as they're helping her close up the store. Leo grins at Amy, who pushes him away by the nose playfully. Warren gets run over by a passing truck. "For I am Warren Stone, former number one news anchor and the greatest foe of the teenage mutant loser turtles and their brunette friend!" But in his videos, it's as if to the five he doesn't exist at all, since they didn't notice him or realize his presence. An oozesquito passes by in his home as he laughs to himself, checking his watch.
"Ooo, I'm late!" He jumps and lands on his face before turning on the TV to the news.
"I am Carley Montonvera, filling in for the completely forgotten Warren Stone," Warren growls at that. "The search for missing hypnotist, Mezmer-Ron and his hippopotamus, Doug, continues," No one takes note of the oozesquito lurking around. "In unrelated news, a monster hippo in a magician's tuxedo is terrorizing local magicians and stealing their trick animals." Footage shows children crying outside a theater. "And with no animals, there's no magic."
"News flash!" Warren yells, "Those wannabe hero turtles and Amy will be hot on that mutant hippo's trail, which will make setting a trap for them soooo easy," He notices the camera panning away from him and moves back in place, adjusting his collar. "With their destruction coming in my hands, I won't be reporting the news, I'll BE the news!"
A large hippo spins around in the air, landing at a ladder. It falls and the hippo screams, landing on a rooftop. The hippo looks around rapidly before walking up to a rooftop. The hippo pulls off its head before it turns out it's just Raph in a large hippo costume.
"You're sure that evil mutant hippo is around here?" He calls out, the others revealing themselves. Leo sits on the edge, holding his weapon on his shoulder. Amy pulls up on her bike near the edge, having been upgraded by Donnie. It can withstand any terrain and it creates as many seats as she wants. It's also less heavy and has a few weapons as well. "It's a million degrees in this thing."
"Uh, I'd be happy to wear it," Mikey puts on the head. "If you need a break."
"No, no, no, no!" Raph snatches the head from him, hugging the head. "I'm the leader. The leader wears the suit."
"Well, I mean he's got a point. Raph is the most hippo-like," Leo jokes, causing the other four to snicker. Leo leans in closer, raising his eyebrows at Amy. She pushes him away by the nose.
"Nice try, wonder turtle." She brushes some dirt off of her ruffled skirt.
"If I'm gonna attract him, I need a little more of that female hippo scent." Donnie and Mikey glance at Amy, who sighs and throws her perfume from behind. Donnie catches it and sprays Raph with it. "Dazzling fresh."
"You owe me another one," Amy points at Donnie.
"Help!" They hear a voice and turn around.
"That must be him."
Amy revs up her bike, jumping over the edge and landing on the road with no difficulty.
"A hippo magician is trying to saw my magic worm in half!" The voice sounds familiar as they reach the park in the kids' area. Two glowing signs point to the worm: Warren Stone in disguise. They peek over the jungle gym and the signs fall down.
"Does anyone else find this whole thing a little..." Leo starts off.
"Odd?" Donnie suggests.
"Magical?" Mikey asks.
"Suspicious?" Amy eyes the worm in disgust. She's left her bike behind.
"Totally legit!" Raph exclaims, jumping down. "Don't worry, Raph will save ya!" The crash is so powerful, Warren is out of his box. He quickly slips back in, but Raph finds himself stuck in fly paper. "Uh. Hey, hey, Raph's stuck." He wiggles around and Leo sighs, facepalming.
"Not again." The others jump down, Donnie and Leo trying to get him out. Warren laughs evilly, getting their attention.
"Stepped right into my goop trap!"
Raph lifts his head. "Your what now?"
"Goop trap!" Warren elaborates, Mikey sliding down the slide.
"Talking magic worm?!" He exclaims in awe.
"That was all a ruse," Warren takes off his disguise, "For I am Warren Stone," He takes on a pose, "Your greatest foe, and-"
Leo pokes his hair as Donnie and Amy examine him. "I'm sorry, Warren who?" He moves around the blonde hair.
"Stop it!" He waves Leo's hand off. "Stone, I'm-I'm your greatest-"
"Oh, don't tell me," Leo interrupts, laughing. "What are you, Worm Man?" Donnie pays no attention to him, Amy snickering at the name.
"Or maybe Worm Boy?" Either way, the lame names would suit him.
"No, no, no, I am-"
Raph lifts his head off. "Can someone help me get unstuck?" He asks impatiently, Leo rolling his eyes.
"Fine," Leo and Donnie walk over to him.
"Mellie, get over here."
"Don't you tell me what to do, you big oaf," Amy retorts as she walks over, trying to help Leo pull him. Mikey is swinging on one of the horses, not bothering to help at all.
"Um, greatest nemesis here," Warren calls out to get their attention and Amy turns to him with an angry look. Honestly, she had no idea what his problem was, and she didn't care.
"Don't know you and don't care. Now get lost," She raises a leg and taps her foot against the ground, electricity hitting Warren and electrocuting him slightly.
"Stop!" He yells at them, shouting and jumping to attack, but lands right on Leo's face with a loud 'plop.'
"Aah, get it off of me! Gross!" He screams, Amy laughing at him.
"Classic mistake. I may be small, but I'm also very-" Leo smacks him off his face and he turns around before cutting Warren in half! He falls onto the ground, looking dead as he doesn't move. Amy screams, covering her mouth. Just because she doesn't like mutants doesn't mean she wanted to see them dead.
"Oh! WHAT DID YOU DO?!" Raph shouts at his younger brother.
"He was on my head, I panicked!" Leo yells back in argument, his teeth chattering as he just killed a mutant. Amy looks around in shock with her mouth still covered, wondering if anyone saw that.
"Is he gonna be okay?" Mikey wonders.
"IS HE GONNA BE OKAY?!" Raph repeats, Amy covering her ears.
"Ugh, shut up!" She exclaims in annoyance before the other worm half crawls onto her shoe.
"He's in two pieces!" Raph points to it and Amy looks down, screaming in horror. She kicks in the air, the half falling near Warren.
"That's disgusting!" She scrambles away onto Leo's shoulder and he smirks down at her. Her eyes quickly look up at him before she moves away, dusting herself off.
"You fools!" He suddenly wakes up, shocking the others. They back away in panic, Leo ready to defend himself if needed. Warren clutches his chest as veins crawl up his face. "You've unleashed my ultimate power! Now I can-"
"You can clone yourself?" Mikey interrupts.
"No," Warren explains, "I regenerate. It's an amazing power, but it's incredibly painful."
Amy suddenly gets shocked slightly and her hair is covered in soot, along with her clothes. "That makes two of us," She drawls with narrowed eyes. As the turtles learned a short while ago, if Amy doesn't use her powers once in a while, they react on her own and shock her. Which meant she still needed to learn how to control them more.
"Fascinating. How long does the regeneration process take?" Donnie wonders.
"Several...days," He explains.
"And you grow back with double the strength," Mikey pumps his muscles.
"No," Warren mutters to Mikey's disappointment.
"But four times the size," Raph assumes, to Warren's confusion.
"If I don't grow back twice as strong, why would I grow back four times as big?" Warren retorts, trying to speed up the process.
"I don't understand you," Leo says slowly.
"Listen, I think there's been a misunderstanding. You see, we don't know you and we don't want to know you. So why don't you just sit there and...regenerate," Amy uses that term loosely. "While we deal with our own business?" She shakes off the soot and walks over to her bike, followed by the others. Amy pulls down her sunglasses and puts on her helmet.
"Go get some pizza now?" Raph suggests, "I'm hungry."
"Are you sure he's gonna be okay, guys?" Mikey asks as Amy presses a button, extending the back for 4 extra seats.
"Oh, I'm fine, you slumped stinking county fair prized losers!" Warren calls out, hopping up and down.
"You heard him scream, he's fine," Raph says as they climb onto the motorcycle, sighing. "I had my fists set on busting up a magic hippo. What a waste."
"Oh, I'm sure he doesn't bite," Amy waves it off as she hops into the driver's seat. "He's all bark and no bite."
"I call shotgun!" Leo jumps into the seat behind her. "And by the way, my lady, you're too good enough for a county fair."
"Gee, I'm so flattered," Amy murmurs sarcastically, turning the handle and taking off with them. At least Leo had made her laugh, that was something.
"They want to fight a magic hippo?" Warren mutters to himself. "I'll give them a magic...worm."
A door opens to a shop, where a human is eating a chocolate bar at the counter. "Uh, an anonymous source told me this is where you get...enhancements?" The cashier looks at the customer, who has robotic legs. "Mutant enhancements?" It's just Warren in a disguise, though. "Mystical mutant-"
"You're just supposed to say the password, wink," The cashier puts on air quotes when he says that. Warren removes his costume, shrugging.
"Okay...wink?"
The cashier removes his hat. "Yup, you did it again, Clem. Wink is the password," He turns into a mutant goat. He looks like he's about to slam the bell, but just taps it lightly. The shelves behind him turn green and dark, showing off what Warren was wondering about. He jumps up to the counter and his eyes shine on a blue gem.
"Give me the blue..." He points to it and Warren is handed the gem, seeing his face on it. "Now, gimme your phone. He dials the police. "Yes, I'd like to report a rampaging hippo outside the burgundy center." The police chief nods before he sends two officers to the scene. "What, my name? Uh...current occupant!" He throws the phone back to the shopkeeper. Warren places the gem on his chest, laughing manically as the gem starts to glow. The police pass right by the store, not even noticing the glowing. The police car passes by a building, the turtles and Amy already there.
"Are you sure the hippo's in there?" Leo wonders.
"Uh, yes. I picked it up on my scanner. A 'current occupant' called it in," Donnie explains, cutting open a circle in the rooftop window.
"Now explain it to me again," Raph has his arms crossed as he's out of the hippo costume. Mikey's wearing it instead. "Why can't I wear the suit?"
"We've been over this," Leo rolls his eyes. "Ames is too small for it."
"And you ruined that woman's 95th birthday," Donnie reminds him.
"She's fine!" Raph argues as Amy pulls out a card.
"On the other hand, you got me a new customer, so thank you in advance," She pats his shoulder.
"I'll do you in the suit proud," Mikey places an arm around his pouting brother.
"Treat it with respect. And be careful," Raph kicks him into the room, the others landing on the lights. Leo pulls the spotlight onto him. Mikey strikes a pose, to Leo's confusion.
"Uh, what is he doing?"
"Some mate dance he saw on Nature Planet," Donnie explains, Amy shaking her head. Mikey slides to the side.
"Hippo! I'm right here!" He shakes his tushy.
"Hippo man?" Leo says into a microphone. "Your biggest fan is here! She loves magician's animals. Bunnies, doves, tigers, and was hoping you brought some."
"And she's quite a looker," Amy calls out, glancing at the dancing Mikey. "...If you're into that."
"I hope he likes me," Mikey murmurs, continuing to dance.
"He will. Of course he'll like you, you're adorable. But you're even more adorable, my pink-a-boo," Leo places a fist to his chin, leaning towards Amy. She stands up and joins Mikey near a desk, ignoring him. Leo just shrugs. "Everyone's a critic."
"Breaking news!"
They turn to the desk, ready to fight the hippo. The four spotlights turn to the desk. "You may have beaten me before, but I'm a little tougher this time." Purple hands clap as the chair turns around. "You see, I've enhanced myself. I've really grown into my role as your greatest nemesis! I'm really 'pumped' for our little test!" Warren reveals himself in a buff body and they look in disgust.
"Jumping Jack Flash!"
"Okay."
They stare at him, Amy looking away. "You're not a hippo...are you?" Raph asks to Warren's irritation.
"No I'm not a hippo! Do I look like a hippo to you?" He flexes his new muscles, Donnie measuring him.
"Hm, maybe a baby hippo?" He suggests.
"He looks like something, alright," Amy murmurs to Raph.
"I am not a hippo and please stop interrupting me! I called in the hippo sighting," He exclaims, Mikey removing the head.
"Guys! H-He's current occupant!" Mikey realizes, pointing to him.
"Oh cripes, not another one of your 'traps'," Amy facepalms, getting annoyed with the worm pestering them.
"See, he gets it," Warren gestures to himself. "I am current occupant."
"And we're here to save you from the hippo magician. Where is he?" Mikey disregards him and puts the head back on.
"No, you green idiot! It was a ruse! There is no hippo! I'm Warren Stone, your greatest nemesis! Prepare to meet-" Something crashes into the building behind him, revealing the real mutant hippo. He's large with dark grey skin and has yellow eyes with red pupils. He has his black hair and goatee, as well as the same outfit he was wearing before his mutation.
"Ta da! Hypnopotamus has arrived!" His three razor rings land in his hand and Warren growls at him. Raph pushes him away.
"Finally, the thing we actually care about," He pushes Mikey. "You're on, Mikey." The costume smells of Amy's perfume, which attracts the hippo mutant. He slides right over to Mikey and dips him. "Hello, future Mrs. Hypnopotamus." He winks at Mikey, apparently attracted to him.
"You tease. Oh my," Mikey fake swoons as Hypnopotamus makes kissy noises, grossing out Leo and Amy while doing Raph ad Donnie proud. Mikey slides over to them, revealing his true face. "See? My hippo is more hippo-ey."
Hypnopotamus continues kissing the head before he realizes that it's a ruse. He screams, looking around and seeing the turtles. They laugh sheepishly, Amy rolling her eyes.
"Pulled the old 'False Ginny' on me. Ugh!" He groans, closing his eyes. "I gotta say, this has been the worst mating season." He takes a look at Amy, smelling the same scent. "Or maybe not!" He pulls out his three rings and they float in the air.
"Oh, that is a well-dressed mutant hippo," Leo points at him and they ready their weapons.
"Fellas, and Mellie, let's smash this guy!" One by one, they dash towards him as Warren looks up, having been cut in half by the explosion.
"No, smash this guy! This one right here! Me!" He tries to grab them, but fails. "Oh, come on!"
Leo jumps up to attack, but he blocks with one of his rings. Amy jumps up next, ready to use her spear, but Hypnopotamus grabs her in his hand.
"Put me down!" She struggles in his grip.
"How would you like to be the future Mrs. Hypnopotamus?" He sniffs her perfume and she groans.
"How about I puke? I told you guys we shouldn't have used my perfume," She hacks up her throat and spits in his face, making him drop her. He attacks them all using his magic and Raph leaps into the air, using his smash jitsu. The hippo moves out of the way, throwing his rings. Raph punches them and moves back, covering his area before the others laugh at him. They jump into the air, but Hypnopotamus is prepared for them.
"Mezmer-Roon!" He uses a shout to put them into a trance, laughing evilly. "Now, which one should I take care of next?" He gestures to Raph. "Big Red? Baby Blue?" He looks at Leo next and then Amy, taking note of her blonde locks. "Barbie Lou? No," the hippo chuckles, "I think I'll start with you, you jiving trickster," He moves a ring near Mikey. Warren scoffs at him.
"Some nemesis," He rolls his eyes. "He doesn't even know their names." He looks down and sees a discarded trophy of his former self, smiling to look like himself again...he growls and turns to the hippo as he's holding Mikey. He then looks to his gem as the mutant slams down Mikey.
"This could get messy. Like me gum boots in a downy drench," He throws the ring at Mikey, but Warren gets in the way.
"Breaking news," The ring is caught into his hair as he crosses his arms. "If anyone is gonna end these guys, it's going to be me!" He removes the ring and throws it away.
"Sorry, who-who-who are you?" Hypnopotamus bends down to him, catching his ring.
"Warren," His hair splits in half and he licks his hands, fixing it. "I'm Warren 'Bad Boy' Stone. I hate these turtle punks and Amelia more than anyone. And that's why I have to stop you!"
The hippo just laughs at him, "I'm laughing. Prepare to be Mezmer-rooon," He fires the trance from his mouth again and Warren looks at his gem.
"This is really gonna hurt," He removes the gem from his chest and uses it to reflect the blast back to the mutant hippo. He's put into his own trance and falls onto the ground. The gem falls onto the ground, breaking it into pieces. Warren falls onto the ground, no longer tall and buff, but now naked. "Turtles, Amelia, finally we can start-" Leo lands on him, rubbing his head.
"What just happened?" He murmurs to himself as the others snap out of it. They have no memory of the previous events. Raph steps on the mutant hippo's chest.
"I think we won."
"My plan must've worked," Donnie shrugs as Amy looks down at him.
"And it was my plan to use your plan. You're welcome, everybody," Raph crosses his arms, Donnie looking annoyed.
"I think by rejecting him, I broke his heart," Mikey removes the costume, pushing it into Donnie's arms. "Whew, sheesh, this has too much power!"
"Considering how it's pink-a-boo's, it works," Leo leans on Amy's shoulder and she pushes his face away.
"Well, at least the jolly old kids can be happy again," Amy crosses her arms with a small grin.
"No!" Warren shouts and they look around before Leo shows Warren stuck in his...well, derriere. "I saved you losers turtles by hypnotizing that beast and saving your lives!"
"You wanna help me?" Leo smirks at Amy.
"I am not touching that turtle booty," Amy moves away and Leo pulls Warren out, ripping him in half.
"And you are?" Leo asks, Warren pouting in anger.
