Dakota lays on her back near Asher, the soft purple blanket beneath them acting as the perfect space for them to rest and look up at everything. She stares up at Donatello as he works, his tongue poking out of his mouth as he manufactures more human patches. Her one red eye flashes as she watches him work, Asher cooing nearby as he too looks up at his father. Both children seem to love watching their parents working, even at such a young age.

Donnie glances at his children, monitoring them. They're growing so fast, something he knew to expect with children. As he later discovered, Asher and Dakota are about a month younger than Mitch. In turn, Mitch is around one month younger than Copeland, and Copeland is two months younger than Dean.

In short, that just means that there's a lot of babies in the lair all at once.

Metalhead clanks towards Donnie, narrowly missing the blanket near the turtle. Donnie gasps, lurching to his feet and putting a hand on the metal turtle's chest.

"What are you doing, Metalhead?" he demands. "You have to be careful!"

Metalhead lets out an apologetic beep. Donnie purses his lips as he kneels down and lifts Asher off the blanket, ruffling his son's thin brown hair as he sets him on a spacious spot on the lab table. He quickly retrieves Dakota and sets her in a nearby spot, retrieving their blanket as he switches everything around and makes them comfortable.

"Look," Donnie sighs, still talking to the robot. "I'm just going to get one of the other girls to look after them until I finish this batch."

As Donnie pulls out his t-phone and dials the number, Metalhead glances towards the babbling babies on the table, his glowing blue eyes seeming to narrow. Although he can't feel jealousy, this is certainly the closest thing he's ever gotten to it.

The robotic turtle spins around and stomps back to his designated spot, but does it less carefully. His arm bumps the table, jostling a nearby canister of mutagen. Before anyone can stop it, the canister tips over. The lid pops off and splashes, hitting the nearest person to it.

That person just so happens to be Asher.

Donnie jumps as he hears his son squeal in surprise, spinning around. He feels his heart stop for a second when he sees his little boy splattered with mutagen, his tiny body already starting to shift.

Right before his eyes, Asher transforms. His skin turns green, his hands getting larger and losing a few fingers as a shell and plastron grows, tearing apart the violet onesie he'd been wearing. Donnie's mouth falls open, taking in the newly-mutated baby turtle.

He moves closer, lifting his son from the puddle as the last of the substance slips off his skin. His mismatched eyes remain, as does his brown hair. He looks even more like his dad now, which makes sense considering he mutated into the last living thing he touched.

"Oh no...oh no..." Donnie says, staring at Asher. "I mutated my kid."

A sharp gasp sounds from the doorway, causing him to spin around. Sarina holds a few grocery bags, her mouth hanging open.

"Donatello...is that..." she starts, setting the bags down.

"Uh...well, you see...I..." he stammers, his gaze flickering between his stunned wife and seemingly oblivious son. "Yes, it's Asher. The mutagen somehow tipped over and splashed him!"

"I told you that the babies don't belong near any chemicals or alien substances," the cyborg scolds.

"Well, we can make a retro-mutagen," he suggests with a weak smile.

Sarina walks forwards, brushing past him to lift Dakota into her arms. She looks to her daughter, then at her son and husband. Her eyes flash as she smirks.

"Actually...I like him as a turtle. He looks like you," she comments.

Asher giggles with glee as he claps his hands together. Donnie laughs as he bounces his son lightly.

"Well...then it's a happy accident, hm?" he asks.

Sarina smirks. "Indeed."
