In the subway tunnels, Michelangelo shifted impatiently, bouncing on his heels. "Ugh, what's taking so long? Donnie knows I have a short atten—Ooh, gum!" His eyes lit up as he spotted a discarded piece stuck to the tunnel wall.

Mari, standing beside him, wrinkled her nose in disgust. "Oh my god, Mikey, do not put that in your mouth."

Mikey huffed. "I wasn't going to! ...Probably."

Raph rolled his eyes. "Man, this better be worth it."

"I wonder what it could be!" Cat giggled, excitedly.

As if on cue, the sound of an approaching subway car rumbled through the tunnel. But this wasn't just any subway car.

The modified subway bus screeched to a halt in front of them, gleaming under the flickering tunnel lights.

Raph's skepticism melted into wide-eyed admiration. "Okay... worth it."

Donnie climbed out of the driver's seat, beaming. "So?"

Leo's brows lifted in surprise. "You turned Leatherhead's old subway car into this?"

Raph let out an impressed chuckle. "Donnie, have I ever told you how awesome you are?"

Donnie tilted his head. "No, you haven't."

"Well... I'm seriously considering it."

Mikey, meanwhile, had thrown himself against the side of the vehicle in an affectionate hug. "Dude. It's beautiful."

Mari circled the Shellraiser, tapping the reinforced plating. "I hate saying this, but... I might actually be impressed."

Cat, wide-eyed, clutched Mikey's arm. "I am so ready for this thing to be my new personality."

Leo ran his hand along the exterior, taking in the reinforced armor. "What do you call this thing?"

Donnie's eyes lit up as he straightened his glasses. "Well, technically, it's a transaxled, multi-armored, electromagnetic—"

Mikey cut him off, throwing his hands in the air. "The Shellraiser!"

Donnie blinked. "What?"

"The Shellraiser!" Mikey repeated, bouncing on his heels. "It's perfect!"

Leo considered it for a beat before nodding. "That is the perfect name."

Mikey smirked. "Of course it is, bro. You guys always underestimate me. Ooh, gum!" He made a grab for another stray piece stuck to the side of the tunnel.

Mari smacked his hand away. "DID WE NOT JUST TALK ABOUT THIS?!"

Donnie ignored them, already moving toward the vehicle's interior. "Alright, listen up. I've assigned everyone to a station based on individual skill sets."

As the others clambered inside, Donnie gestured toward the driver's seat. "Now, I can't drive, because my station's in the back, so—"

"Driver!"

The word erupted in unison as everyone lunged for the front seat.

Instant chaos.

Arms shoved, hands grabbed, arguments flared.

Donnie sighed. "Leo drives."

Mikey, Cat, Mari and Raph stopped mid-struggle to turn toward him. "Why?!"

Donnie adjusted his glasses. "He's the least likely to hit something just for fun."

The four blinked, considered it for a second, then all sighed. "True."

Everyone settled into their assigned stations as Leo strapped himself into the driver's seat. His fingers curled around the controls. "Alright, so how do we get this baby going?"

Donnie leaned forward, pointing at the controls. "Okay, just ease the throttle forward ever so sli—"

Leo pressed forward.

The Shellraiser lurched violently, sending everyone jerking in their seats.

Cat shrieked. "I HATE THIS!"

Mari, gripping the dashboard, shot Donnie a glare. "What the hell, Donnie?!"

Raph, gripping his seat, demanded, "What is powering this thing?!"

Donnie, already bracing himself, straightened his glasses. "The Kraang power cell we got from Leatherhead."

Leo frowned. "I thought you said that thing was dangerous. Like, the Kraang could track it dangerous."

"That's why I put it under a lead glass shield," Donnie assured him. "Now I can regulate the output and prevent the Kraang from detecting its signal."

Mikey, still gripping the armrest, pointed ahead. "Uh, guys? DEAD END!"

Leo's grip tightened on the controls. "Donnie, how do I stop this thing?"

"Don't!" Donnie called out.

Leo's eyes widened. "WHAT?!?"

"Trust me!"

The Shellraiser sped forward—straight toward the tunnel wall.

Everyone screamed.

At the last second, Donnie slammed a button.

The ground rumbled.

A hidden ramp deployed.

The Shellraiser shot up, launching through a hidden exit and bursting onto the city streets in a spectacular reveal.

Silence fell as the realization sank in.

Raph let out a breath, nodding in genuine appreciation. "Donnie... you're awesome."

Donnie grinned. "Yeah. I know."

Mikey leaned forward in his seat, eyes glinting with excitement. "This thing have a stereo?"

Donnie smirked. "What good would it be without some tunes?" He flipped a switch, and the cabin filled with the soft, elegant sound of classical piano.

Raph blinked. "Are you serious?"

Mari groaned, rubbing her temples. "Oh my god, Donnie."

Donnie held up a finger. "Check out the second movement."

Suddenly, the music shifted into a heavy rock riff, shaking the Shellraiser with its deep bass.

Mikey let out a cheer, bobbing his head to the beat. "Now we're talking!"

Cat, arms crossed, muttered, "Okay, but the classical was kinda nice..."

Leo grinned as he gripped the controls. "Alright, let's see what this baby can really do."

The Shellraiser roared forward, its massive tires gripping the city streets as the team cheered.

But Raph suddenly perked up, narrowing his eyes at the screen displaying the street ahead. "Leo, pull over."

Leo brought the vehicle to a smooth stop. The others leaned forward, watching the monitors as a group of familiar figures came into view.

Leo let out a laugh. "Purple Dragons? Oh, this night keeps getting better and better."

Raph cracked his knuckles. "Oh, yeah. It's like candy for my knuckles. And tonight's Halloween."

Donnie squinted at the screen. "Wait a minute... who's that?"

A lone figure stood near the Purple Dragons, clad in a homemade turtle costume. The green fabric sagged in awkward places, and the foam shell on his back looked more like a school project gone wrong than actual armor.

The man struck a dramatic pose. "Excuse me, boys. I think you forgot to pay for that. But don't worry—I accept cash, check, or teeth."

Leo raised an eyebrow. "Huh. That was a pretty good line."

One of the Dragons, Fong, smirked. "What are you gonna do? There's one of you and three of us."

The man puffed out his chest. "Oh, you wanna call a couple friends? Make it even?"

With a rather clumsy motion, he hopped down from a dumpster, landing awkwardly but determined.

Raph snorted. "This guy's got guts."

Mari leaned forward, unimpressed. "He's got a death wish."

The man pointed a shaky finger at the gang. "It's time to face the wrath of... The Pulverizer!"

Mikey gasped, eyes gleaming with anticipation. "This is gonna be great."

Except—it wasn't.

The Pulverizer charged in with all the skill of a wet noodle, throwing punches and kicks that barely landed.

"Hyah! Judo!" He swung wildly. "Punch, punch! Hyah!"

Leo cringed. "Or not."

The gang barely even flinched. Then, without hesitation, they retaliated.

One punch.

Then another.

Within seconds, the Pulverizer was getting absolutely wrecked.

The Turtles winced as the beatdown continued.

"Ooooh," Mikey winced. "The Pulverizer's getting just... well, I don't know the word, but we gotta help him."

Cat winced, gripping her tessen. "This is actually painful to watch..."

The Purple Dragons stood over the crumpled figure of the Pulverizer, laughing as they cracked their knuckles.

Leo exhaled. "How do you like the odds now, Fong?"

The gang barely had time to react before the Turtles leaped into action.

The fight was over in seconds.

Timothy, still groggy from his pummeling, stumbled to his feet. His eyes widened as he took in the sight before him. "Whoa, the Turtles!"

Donnie frowned, startled. "How does he know who we—"

Before he could finish, a punch flew toward him. He dodged just in time, retaliating with a swift kick.

The Pulverizer, attempting to join in, threw a punch—except he hit Donnie instead.

"Nice combo!" Timothy cheered. "High five!"

Sid, one of the Dragons, promptly threw Timothy onto Donnie, knocking them both to the ground.

Mari sighed, muttering. "This is embarrassing."

Leo cursed under his breath as he spotted Fong making a run for it. "Fong's getting away!"

Mikey's eyes narrowed. "Oh, no, he don't."

Before Mikey could intervene, Timothy bolted forward. "I got him!"

Except—he didn't.

With one misstep, he tripped over himself, landing flat on his back. Mikey barely managed to dodge the collapse.

Timothy groaned. "Oh, dang. Almost had him."

Mikey glared. "Not cool, man."

The distant wail of police sirens cut through the air.

Leo's instincts kicked in. "Cops! We gotta go!"

Timothy scrambled up, looking between them with excitement. "Oh, hey, uh, great teamwork, guys!"

Raph rounded on him, fuming. "*Look, I don't know who you think you are, or what you think you're doing, but don't."

Timothy ignored the warning, still grinning. "Yeah, maybe sometime we can get together and—whoa!" He took a step forward, but his foot caught on something. "Wait, I think I—whoa! Yahhh!"

His flailing hands caught onto the Shellraiser just as it roared off into the night.

The Turtles didn't notice.

Leo kept his eyes on the road. "You guys hear something?"

There was a faint, distant yell.

"Nah," Mari muttered, stretching out in her seat.

Back at the lair, the Shellraiser screeched to a halt.

The Turtles hopped out one by one—only to hear a thud behind them.

They turned.

Timothy lay sprawled on the ground, groaning.

Donnie ran a hand down his face. "We got a problem."

Leo took a cautious step forward, eyes narrowing. "What the—?"

Car crouched beside him. "Are you okay?"

Timothy groaned, managing a weak thumbs-up. "Uh, sure. You can survive with just one kidney, right?"

Cat winced, rubbing her temples. "I don't think that's how that works..."

Raph threw his hands up. "Great. First this doofus gets in the way of a good Purple Dragon stomping, and now he knows where our lair is."

Timothy waved a dismissive hand. "Oh, no problem. I blacked out most of the way here."

Donnie pinched the bridge of his nose. "Fantastic."

Leo crossed his arms. "How do you even know we exist?"

Timothy sat up, dusting himself off. "Oh, I saw you months ago."

"You were like, 'Let's finish this!'" he said, pointing at Leo. Then, he turned to Raph, throwing a few exaggerated punches. "And you were, like, 'You're going down!'"

His attention shifted to Cat, and he waved his hands wildly. "And you—you were all, 'Bees!'"

Cat blinked. "Wait, bees?"

Timothy didn't slow down, spinning toward Donnie, who had remained silent, arms crossed. "And you," he continued in awe, "you were, like... the strong, silent type." He glanced at Mikey, "the funny guy, and you.." He looks at Mari, "the mean one—"

Mikey's mouth dropped open. He turned to the others. "Dudes, we have a stalker."

Timothy ignored him, standing up excitedly. "You guys inspired me to become a hero! I saw you in action and thought, 'What do they have that I don't have?'"

Donnie raised a brow. "Oh, I don't know... years of training under a grand master of ninjutsu?"

Timothy grinned. "Nope! An awesome costume." He gestured to the sagging foam turtle shell strapped to his back. "Where'd you guys get yours, by the way?"

Donnie's expression flattened. "We're not wearing costumes. We're mutants."

Timothy gave them an easy nod. "Right." He squinted at them as if trying to figure out the logistics. "Cool. So how do I do that?"

Raph groaned. "You, stop talking." He turned to Leo. "We gotta get this guy outta here."

Before anyone could protest, Mari, arms crossed, deadpanned. "Yeah, seconded."

But Timothy gasped, spinning in a slow circle as he took in the lair. "Whoa, this place is amazing!" His eyes landed on the stacks of pizza boxes shoved against the wall. "What's with all the pizza?"

Cat, sitting off to the side, raised an eyebrow. "What kind of question is that?"

Timothy, already wandering, reached for a piece of tech on Donnie's workbench.

Donnie snapped. "Hey! Don't touch that!"

Timothy ignored him, picking up a small, metallic device. His eyes widened. "Hey, this looks just like the stuff those guys were stealing earlier!"

Donnie's stomach dropped. He swiped the device from Timothy's hands. "That's impossible," he muttered. "This is Kraang tech."

Timothy blinked. "What's a Kraang?"

Raph grinned, slinging an arm around Timothy's shoulders. "If we told you, we'd have to kill you."

Timothy paled.

Mari smirked. "Please let me be the one to do it."

Donnie sighed. "They're aliens. From another dimension."

Leo crossed his arms, gears turning in his mind. "Wait—why would the Purple Dimwits want Kraang robotics? It's not like they'd know what to do with it."

The realization hit all at once.

"Unless..." Donnie said slowly, dread creeping into his voice, "they're stealing it for someone else."

Leo, Raph, Mari and Donnie shared a look.

"Baxter Stockman," they said in unison.

Mikey and Cat said, "Donatello, I mean, Baxter Stockman!"

Leo sighed, already heading for the exit. "We'll check it out. Donnie, fix the Shellraiser and take Captain Rubber Pants home."

Donnie gaped. "What?! Wait! Why do I have to—"

Before he could finish, Timothy spun around, grinning ear to ear. "So what now?" he asked eagerly.

Then, in one swift motion, he turned—

—and knocked over a rack of beakers.

Glass shattered across the floor.

The lab was dimly lit, the air thick with the scent of oil and burning circuits. The Turtles moved cautiously through the cluttered workspace, past half-built machines and scattered robotic limbs.

Mari walked beside Raph, eyes scanning everything. "This place smells like a toaster on fire."

Cat lingered at the back, unease written across her face. She didn't say anything—but she didn't have to.

Leo stepped forward, voice cutting through the silence. "Baxter Stockman, whatever you're up to with those robotic parts, it ends now."

From the shadows, Stockman chuckled. "You want to see what I've been working on? Well—here it comes."

A low mechanical hum filled the air as something heavy stepped forward. From behind the wreckage emerged Fishface—only now, he was no longer slithering.

He had legs.

The team froze.

Then—

Laughter.

Leo smirked. "Look! Sushi that delivers itself."

Fishface's eyes narrowed. With a snarl, he lunged—his new robotic legs propelling him forward at a terrifying speed. He kicked a toolbox in their direction, sending it flying.

The team scattered.

Mikey flipped backward and landed in a crouch. "Dude, Fishface is way too sensitive."

Leo arched a brow. "You're calling him Fishface?"

Mikey shrugged. "Well, it was that or Robocarp."

Mari snorted. "Robocarp was the right choice."

Before anyone could react, Fishface lunged—kicking Mikey square in the chest and knocking him flat.

Mikey wheezed. "Pretty good... pretty good."

Raph cracked his knuckles, stepping forward. "Important safety tip: avoid the legs."

He rushed in, dodging one of Fishface's swift kicks and twisting around to grab onto his new robotic limbs, attempting to pin them.

Raph grinned. "What do you got besides legs?"

The answer came instantly.

Fishface lunged—sharp teeth sinking into Raph's shoulder.

Pain exploded through him.

His grin vanished.

His vision swam.

His entire body locked up before suddenly giving out, collapsing onto the floor.

Cat's eyes widened. "Raph, you okay?"

Raph blinked blearily, his pupils unfocused. He swayed slightly, a dopey smile crossing his face. "Huh? Sure... yeah."

Sid rushed toward him, but Mikey whipped his chain, knocking the thug away.

Mari lunged forward, catching Raph before he fully collapsed. "No, no, no—stay with me, big guy." She shook him slightly.

Raph's head lolled, his expression softening as he looked at Mikey. "I love you, man."

Mikey gasped. "HE'S NOT FINE!"

Leo's expression turned grim. "Call Donnie. Tell him we need an antidote."

Donnie sat cross-legged in the dojo, forcing himself through another training session with Timothy. His exhaustion was evident, sweat dripping from his brow as he struggled to maintain balance.

Timothy, however, was determined.

"Put your left leg here," Donnie instructed, "right leg there—twist your hips—"

Timothy grinned. "And down you go!"

Donnie blinked. "Wait, wha—?"

A second later, his world flipped.

He hit the mat hard.

Timothy threw his arms up in victory. "Yes! I did it! When do I get my black belt?"

Before Donnie could respond, his T-phone buzzed. He rolled onto his back, groaning as he answered. "Donatello."

Mikey's voice rang through the speaker, frantic. "DONNIE! We need help! Raph's been bitten by a giant poisonous robotic fish!"

Donnie frowned. "That's not possible. If he was bitten, it's venom, not poison."

"Interesting, interesting—GET OVER HERE!"

Donnie scrambled to his feet, already grabbing medical supplies. "Hey, do you know how to drive?" he asked Timothy.

Timothy scoffed. "Are you kidding? I've been driving an ice cream truck all summer."

.

The Shellraiser swerved violently.

Donnie clung to the dashboard, his face turning a shade of green not normal for a turtle. "I thought you said you knew how to drive!"

Timothy gripped the wheel, panic in his eyes. "I usually don't go over eight miles an hour!"

Donnie groaned. "Just hold it steady, okay? I gotta mix this antidote for Raph." He pressed a button on his headset. "Mikey, what are his symptoms?"

Mikey's voice came through, hurried. "He keeps telling me I'm the smartest guy he knows."

Donnie's grip tightened. "Okay. He's delusional. How's his color?"

Mikey hesitated. "Uh... green, man. And I mean way more than usual."

The Shellraiser hit a bump. Donnie slid across the floor, gripping a vial tightly. "Does he have any nausea?"

Mikey opened his mouth to answer—then froze.

In the background, a horrible retching noise filled the speaker.

Mikey recoiled. "AH! WHAT THE—?! I KNEW YOU ATE MY PIZZA! YOU LIAR!"

Meanwhile, Leo and Mari were taking hit after hit, Fishface's enhanced speed and strength overwhelming him.

Cat's voice crackled through the comms—as if she had taken Mikey's phone. "Donnie, GET HERE NOW!"

"We're almost there!" Donnie shouted back. Then, his eyes flicked toward the windshield.

A barricade of cars blocked the road ahead.

Timothy's eyes went wide. "Uh, road's blocked. We gotta go around."

Donnie's jaw clenched. "No time. Jump it."

Timothy whipped his head toward him. "What?!"

Donnie's voice was sharp, urgent. "You wanna be a hero? Jump it!"

Timothy let out a weak laugh. "Yeah, uh, about the hero thing—"

"JUMP IT!"

With a panicked yell, Timothy floored it.

The Shellraiser rocketed forward, tires hitting the barricade—then they were airborne.

Inside the battle, Mikey ducked another strike, his body bracing for the impact that never came.

Instead—

CRASH!

The Shellraiser smashed through the fight, sending debris flying.

Fishface snarled, stunned as a massive garbage ball launched from the Shellraiser's cannon, hitting him square in the face.

"AGH!" Fishface roared, tumbling back.

Donnie and Timothy barely had time to jump out before the Shellraiser began sparking violently behind them.

They sprinted toward Raph, who lay slumped against the alley wall, dazed.

Donnie knelt beside him. "Raph! You still with us, buddy?"

Raph blinked sluggishly. "Donnie?"

Donnie nodded. "Yeah, Raph. I'm here."

Raph's expression twisted in confusion. He stared down at his own feet.

Then, in complete sincerity, he muttered, "Why are there fingers on my feet?"

The Shellraiser jolted and skidded to a stop, tires screeching as smoke curled from the cracked lead glass shielding the power cell.

Donnie dropped to his knees beside Raph, heart hammering as he worked quickly, pulling a syringe from his kit. "Hang in there, buddy. You'll be okay."

Raph's head lolled slightly. He blinked up at Donnie with unfocused eyes. "Thanks, magical unicorn..."

Donnie sighed, shaking his head. "Yeah. You're welcome." He pressed the syringe to Raph's arm, injecting the antivenom. Within seconds, Raph's dazed expression started to clear, the effects of the venom slowly fading.

Before Donnie could relax, Timothy clapped a hand on his shoulder, grinning. "That was awesome! We saved him!"

Mari crouched beside Raph, and narrowed her eyes. "We?"

Donnie stiffened.

"We?" he echoed, voice dangerously calm. His exhaustion, stress, and frustration boiled over in an instant. "YOU wanted to stop and SELL ICE CREAM. If I hadn't jumped and smashed through that wall—"

Mikey's voice cut through. "Uh, Donnie? Is the Shellraiser supposed to do that?"

Donnie snapped his head toward the vehicle, and his stomach dropped.

The glass shielding the power cell had cracked.

His breath caught in his throat. "Oh, no. No, no, no—this is bad."

Leo frowned. "What's wrong?"

Donnie turned to them, panic creeping into his voice. "The Kraang can detect that energy signature! We have to get back underground before they come looking for it!"

Before anyone could react, a high-pitched whirring filled the air.

Bright pink lasers rained down.

The Kraang had found them.

Leo gritted his teeth, throwing the Shellraiser into gear. "Hold her steady! We need to move!"

Mari had already drawn her tanto, bracing herself as she spotted movement on the roof. "They're already here!"

Cat flipped open her tessen, eyes sharp as she readied herself. "They're not getting the power cell!"

Raph, still a little wobbly, forced himself up and staggered toward the cannon controls. "I'll take care of these jokers."

Through the cracked windshield, Donnie could see the Kraang droids climbing onto the roof, their metal limbs clanking as they latched on.

Leo cursed. "They're on the roof!"

Mari was already climbing the emergency hatch, glancing back at Cat. "Let's go!"

Mikey followed, muttering, "Why is it always the roof?"

As they climbed out, Mikey's panicked voice rang through the night. "Leo, the Kraang can fly! THE KRAANG CAN FLY!"

One of the droids lunged, jetpack roaring as it tackled Mikey toward the edge. He flailed wildly, barely holding on. "AGHH, THEY CAN ALSO THROW!"

Mari reacted instantly, gripping Mikey by the wrist and yanking him back before slashing at the Kraang's jetpack with her tanto. Sparks flew as the droid spun out of control, crashing into a nearby wall.

Cat, meanwhile, launched herself at another Kraang mid-air, spinning with her tessen as she sliced straight through its wiring, sending it spiraling into the street below. She landed smoothly, flipping her fan shut.

"You were saying?" she called down to Mikey.

Inside, Timothy's eyes were wide with panic. "Wow, no one told me they were robot aliens!"

Leo, still swerving through traffic, shot him a look. "Why would we tell you?!"

The chaos only escalated.

More Kraang droids swarmed the vehicle, their metallic hands clawing at the power cell.

Leo growled. "Not happening." He activated the Shellraiser's side claws, gripping one of the droids midair and crushing it in a sparking heap.

An oncoming car forced Leo to swerve hard.

The Shellraiser spun out, metal screeching as it crashed into a pile of debris.

Leo was the first to recover, yanking his katana free from the wreckage. He looked up just in time to see a Kraang drone rip the power cell from its casing.

"NO!" Leo shouted.

Timothy scrambled toward it. "Oh, no, you don't!"

Leo's stomach dropped. Don't do it, don't do it—

Timothy lunged.

Donnie's heart stopped. "PULVERIZER, NO!"

"I CAN DO THIS!" Timothy shouted, sprinting after the escaping Kraang.

Donnie's eyes flashed with something close to desperation. "YOU REALLY CAN'T!"

Timothy leaped, aiming to tackle the droid—only for it to bat him aside like an afterthought. He crashed hard, groaning as he clutched his arm.

Mari gritted her teeth, barely stopping herself from lunging after him. "Timothy, MOVE!"

Cat was already moving, flipping mid-air before landing in front of Timothy, her tessen outstretched defensively. "Stay down!"

Donnie hesitated—one second too long.

The power cell was slipping away.

His mind screamed at him. Get the power cell!

But then he saw Timothy, struggling, hurt.

And Donnie couldn't let him die for this.

With no choice, he spun, hurling his bo staff with everything he had. The weapon struck the Kraang, sending it skidding across the pavement. The power cell tumbled from its grasp, rolling to a stop.

But the damage was done.

The Kraang retreated.

The power cell was gone.

Timothy groaned, dragging himself up. "Ah, man... Looks like I mucked everything up, huh?"

Mikey clapped a hand on his shoulder. "Hey, bro, it's not your fault."

Leo sighed. "Uh, actually, Mikey? It is."

Mikey blinked. "Oh. Yeah."

Donnie sighed, pinching the bridge of his nose. "Not completely. I'm the one who sent the Shellraiser through the wall. That's what cracked the power cell in the first place."

Timothy hesitated. "So, uh... you think we could pick up our training again sometime?"

Donnie's eyes darkened. "No."

Timothy deflated. "Fine. But I'll be practicing! And I'll be back! Wherever crime may roam, wherever help is—"

"BYE!" the turtles shouted in unison.

Timothy slumped. "Okay..." He turned, trudging away.

Mari exhaled sharply, rolling her shoulders as she slid her blade back into its sheath. "That guy's gonna get himself killed."

Cat scoffed, flicking her tessen shut. "Yeah, and I'm not cleaning up the mess when it happens."

"You know the guy's annoying when Cat doesn't like him," Raph muttered.

Donnie exhaled. "I have to figure out how we're getting that power cell back."

Leo pinched the bridge of his nose. "Which raises the bigger question—how are we going to get the Shellraiser home?"

Later, in the sewers...

The Shellraiser inched forward.

Well—more accurately, Leo, Raph, Mikey, and Cat pushed the Shellraiser forward, straining against the weight of the armored vehicle.

Inside, Donnie sat comfortably at the controls, running diagnostics.

Mari was sitting on the hood, arms crossed, not even pretending to help. "Hey, guys, if you push any slower, we'll get home by next winter."

Raph groaned. "Are you sure the parking brake isn't on?!"

Donnie scoffed. "For the hundredth time, yes! Oh, wait—" A soft click sounded.

The Shellraiser suddenly rolled forward an inch.

Raph's eye twitched.

Donnie smiled sheepishly. "Uh. Try it now."

"DONNIE!" the turtles roared.

Mari smirked.

Donnie winced. "Oops."
