You are living with the turtles and you are just chilling on the couch on you're phone when suddenly you hear a "BOOM!" from Donnie's lab and go investagate

Once you get there you see Raph, Leo, Donnie and Mikey as children?!?!

Y/N: Donnie what the hell happened?

Donnie: My stupid machine malfunctioned and now we're kids again! Plus I don't know when were gonna change back into our normal ages!? He says with child-ish poudy face... What do you do?
