(note: in this you’re a scientist and you’ve brought donnie from the pet store and the others were bought by Hamato Yoshi)

a while ago you’ve found a canister of mutagen in a alleyway after you just got a pet turtle, you named him Donatello, you took the mutagen to your lab and experimented with it, a week after you accidentally left donatello’s enclosure open while you were gone and he wandered around your lab and when you remembered and rushed back inside… he fell into the mutagen and began to mutate…

but it’s been half a month since the incident and you’re surprised by how intelligent he was, he even made some gadgets and helped you out a lot in the lab, and in return you let him go to the high school your friend runs since he also knows about donnie, oh right he’ll sometimes referred to himself as “donnie”, the one thing you can’t get around is why the mutagen him so… curvy…

currently you were home waiting for donnie to get home since he’s late and he finally comes home in a… modakawa dress?!

donnie: boy that was a good party- he then notices you oh no…
