Inside the farmhouse, everybody gathers at the front entrance and stands in formation. Buckets of water sit at their feet, mops and feather dusters in hand, and determined glares on every face.

"Everyone ready?" April asks.

"Casey Jones was born ready," Casey says, flipping his mask down as he takes a confident step forwards.

"Let's do this." Raphael swings his rainbow-coloured dusters the way he would his sais.

Everyone poses briefly. April grips her sponge, Donatello flips his mop upwards, Michelangelo thrusts his duster into the air like a sword, Leonardo wields his spray bottle, Destiny holds a broom at the ready, and Diaval holds a vacuum cleaner, a nozzle in one hand and the dust collector in the other. They let out battle cries and race off in many different directions, ready to make the house look as good as new.

Raphael attacks the book shelves in the living room, leaping upwards and sending clouds of dust into the air. He lands before the fireplace and narrows his eyes, letting out a grunt as he leaps into the chimney, sweeping out the soot and ash.

Michelangelo chucks a bucket of water to Donatello, who catches it on the edge of his mop without spilling a drop, then proceeds to lunge down the hallway cleaning every inch of floor and even some of the walls. Michelangelo flings his kusarigama chain across the open space between the upper level and the lower level in the main entrance hall, hooking it on the far railing. He swings across on the chain, upside down, and comes to a stop next to the chandelier. He dusts the light fixture and hums a happy song.

"Window cleaner on," Leonardo whispers, spraying one of the upstairs windows. He wipes it off and narrows his eyes. "Window cleaner off." He repeats the action for every pane of glass, still muttering, "Window cleaner on, window cleaner off. Window cleaner on...window cleaner off."

"Calm down, Sensei. Those windows will get too clean at this rate," Destiny teases as she nearly dances past him with a broom in hand.

Leonardo rolls his eyes, although a light smirk lifts his lips. She laughs, continuing to sweep with the broom as if the object is her dance partner, spinning and twisting and dipping while flicking her dustpan down to catch the piles of dust.

Diaval shuffles around in the living room, vacuuming the carpets as carefully as he can. The turtles have already moved every breakable item off the rug, leaving him with a defined square to remain inside. Diaval keeps going, even when Raphael sends even more soot from the fireplace back onto the carpet: accidentally or purposely, Diaval doesn't know. He just keeps vacuuming, zoning out amongst the constant drone and the rattling of debris in the cleaner's tubes.

Donatello sees April coming up the stairs and instantly lights up. He swings his mop around like he does with his bō staff, then flicks the end under the handle of the bucket of water and holds it up, flashing a grin.

"Hey, check me out, April!" he calls.

When April walks past and enters the bathroom, ignoring him, he frowns and drops the bucket, spilling the leftover water onto the floor. He starts to mop it up with a lot less exuberance than before.

April scrubs the bathroom walls, a bucket at her feet. She kneels down and plunges the sponge into the warm, sudsy water and wringing it out before reaching back up to the wall and wiping away the stains and spots.

"Looking good, Red," Casey's voice sounds from behind her. She turns to find him relaxing in the empty bathtub, lounging without a care in the world. "Keep up all the hard work," he says, clicking his tongue and winking at her.

April rolls her eyes and straightens up, resting a hand on her hip. "Real funny, Jones," she says. She chucks the sponge at him and splatters water all over his face. "Now stop slacking off and help out," she scolds.

"Anything for you, mon cherry," he teases, pulling the sponge from his face as he grins.

"It's ma che'rie," Donatello corrects, poking his head into the bathroom. He walks in, heading for the tub. "I can help you, April."

Casey starts to climb out of the tub, but Donatello hooks his mop behind the boy's legs, flipping Casey forward and shoving him from the bathroom with a few quick swipes.

"Oh, yeah! Put your dust rag on it," Michelangelo sings to himself as he gets the upstairs walls clean. "Whoo—"

Casey flies into his stool, knocking the orange-masked turtle off balance, and Casey rebounds to race back into the bathroom. Michelangelo tumbles off the stool and down the stairs with a high-pitched shriek.

Raphael starts up the stairs, stopping short when he hears the scream. "You gotta be kid—" His eyes widen when he sees his brother plummeting towards him. "Whoa!"

The two turtles collide, falling back down the stairs and landing on an unsuspecting Destiny. A bucket of water lands on top of Raphael's head, only adding to the chaos. Leonardo limps into the room, Diaval trailing behind out of pure curiosity.

"Oh, Mikey, we just vacuumed!" Leonardo groans.

"Yeah? Well, I'm about to mop the floor with him," Raphael growls, throwing the bucket to the floor as he finally gets it off his head.

"Guys? A little help?" Destiny wheezes, the weight of the two turtles on top of her making it very hard to breathe.

"Whoops, sorry Des," Raphael apologizes.

He shoves Michelangelo off and gets up himself, stooping to help Destiny off the floor. April, Casey, and Donatello start down the stairs as Michelangelo shakes his head in an attempt to stop the spinning of his brain. His baby blue eyes flicker to the floor and gain a few sizes in width subsequently.

"Whoa, guys," the orange-masked turtle whispers. "Check it out!"

The carpet that once covered the front hall has been pushed back, revealing a trap door in the floor. The group gathers around it, staring down at the new discovery.

"A trap door? I didn't even know we had a basement," April admits.

"What do you suppose is down there?" Leonardo asks.

Michelangelo's face flushes as he imagines the cackling, painted face of a carnival clown with flashing eyes. "Evil clown..." he squeaks, hiding behind Raphael. "Evil clown!"

"Only one way to find out," Raphael says, spinning his sais.

With a grunt, he pries the old hinges back and flips the door open, revealing a dark, creaky staircase leading down into a den of cobwebs. Everyone gathers around, eyeing it with varying degrees of negative emotions.

"Uh, who's going first?" Donatello asks, clearing his throat.

"Not it!" everyone shouts save for Leonardo and Diaval.

Diaval panics slightly at the sudden noise and blurts out the same phrase before Leonardo can. He pumps his fist to himself, muttering "win" under his breath, while Leonardo looks around at everyone. They flash pitying smiles and he groans.

With a sigh, the leader in blue starts down the stairs. Raphael goes directly behind him, then Michelangelo, Donatello, April, Casey, Destiny, and Diaval bringing up the rear.

Once downstairs, Destiny is the first to tense up. She lets out a little gasp and stares wide-eyed into the darkness ahead of them, earning looks of confusion from the others.

"Raph, turn on your flashlight," she whispers.

He listens. The beam falls on the beat up shape of a familiar ship and this time, everyone gasps.

"The Kraang," Leonardo says, taking a hesitant step back and casting a quick look to the exit.

"Whoa..." Michelangelo whispers.

"It's impossible," Raphael mumbles.

"It can't be," Leonardo says in disbelief.

"It's a Kraang stealth ship," Donatello concludes.

Diaval makes a low noise in his throat and steps backwards, his heel catching on the step behind him. He tips backwards, but Destiny snatches him by the collar of his cloak and rights him before he can fall.

"Wicked!" Casey grins.

"But...how did they find us?" April asks.

Donatello moves closer to the ship slowly, reaching out and brushing his finger along the side and taking some dirt off with it. "I don't think they did. This ship looks like it's been buried here for years."

"What the heck is a Kraang ship doing underneath my house?" April demands, flinging her hand out at it.

A moment later, a beeping sound emits from the ship and the door slides open with a puff of dust. Donatello steps back and searches the faces of his companions for another reaction.

Leonardo limps forwards, a determined glare settling over his features. "Only one way to find out," he says, moving inside. "Come on."

The teenagers head after him, all except for Diaval. The nineteen-year-old stays rooted in place, staring at the Kraang ship with blown out eyes and a rigid jaw. Destiny tugs at his cloak, giving him a questioning look when he hardly wobbles.

"Don't wanna," he mumbles, shaking his head and making his tiny ponytail smack him in the cheek. "Don't wanna," he repeats with a little more force.

"Diaval, it's been here for..." She searches for some kind of numerical unit of time, but drops it in lieu of, "...a while." She gives him a light smile. "I'm pretty sure there's no Kraang in there." Diaval shakes his head again, remaining firmly planted in place. She sighs and releases his cloak. "Fine, you can stay out here, okay? I'll be back."

Diaval shifts and looks at his feet as she turns and scurries into the ship after the rest of her group. When she emerges into the main bridge, the group is scattered in various places and observing the emptiness of the craft.

"Hey, look," Donatello whispers, pointing a large capsule at the far end of the room.

The others gather closer. Destiny sniffs the air for any kind of scent trail but finds nothing. Casey narrows his eyes and moves up to Donatello's side, peering at the silhouette within the dark capsule.

"Is that a person in there?" he asks.

Destiny sniffs the air again, but the only smells she catches is that of dust and mildew. She frowns and crosses her arms over her chest, her tail lashing as she scoots closer to the gathering teens, bumping Leonardo's shoulder as she does.

Donatello kneels by the capsule. "Okay, don't touch anything," he says, twisting his head to his family. "I repeat, do not...touch...anything!"

He looks pointedly at Michelangelo before he turns back to his work. The turtle grins nervously and backs up, his elbow pad hitting the control panel. The ship powers on with a loud beeping, lights flicking on, and the capsule unlocks with a burst of freezer fog.

"Mikey!" Donatello shouts, turning on his brother.

"Oops." Michelangelo giggles sheepishly as he flings himself away from the panel. "I promise not to touch anything starting...now?"

The container slides open and the cloudy haze within clears out, showing a blonde woman wearing a purple cardigan and plain grey pencil skirt. She groans and blinks, revealing pale green eyes.

April gasps. "Mom?"

"Mom?!" Casey repeats, his face twisting with confusion.

Mrs. O'Neil groans and takes a step out of the capsule only to stumble. Donatello and Raphael sweep forward and catch her, holding her arms over their shoulders.

"Take it easy, ma'am," Donatello warns as she slumps forward, taking heavy breaths.

"Hold on," Raphael adds.

She blinks a few more times and looks up, wagging her head between the two brothers and finally realizing just who or what is holding her up. She screams and elbows Raphael in the gut, breaking from their hold.

"Aah! Mutants!" she shrieks. She dashes for the exit, but her high heels trip her up and she falls, prompting Casey to catch her.

"Oh, uh, don't worry, Mrs. O'Neil," he says, helping her back to her feet and gently grasping her hand. He gestures to the turtles. "These are good mutants." She looks to the four turtles and wolf girl, each of them offering a smile, a wave, or greeting of some kind. "Except for Donnie. He's kind of a jerk."

"Yeah...I—" Donatello starts, but then he realizes what Casey said and frowns. "Hey!"

"Where am I?" Mrs. O'Neil asks, her voice laced with a timid, light lilt. It's like she's telling a bedtime story when the child is almost asleep. "And how do you know my—" She turns to Casey only to look past his shoulder and see April. The woman's face softens. "A-April? But...but how?" She stumbles towards her daughter, her breaths picking up. "Just a few days ago, you were only...six years old!"

Her eyes roll back into her head as she faints, falling back into Casey's arms.

"Mom!" April gasps, reaching out to her. April's head spins and she goes limp, fainting into Michelangelo's arms.

"Snap," he comments under his breath.

Destiny looks between the two girls. "Huh...it must run in the family."
