Donny is your father.

Donny is doing some work in his lab while you sleep in the crib in the corner of the room. The isn't loud or anything, the older turtle mutant is just typing some new code on his computer. Stopping frequently to check up on you, ensuring you're okay and everything is fine.

So, when the turtle mutant heard the tattletale signs of his baby waking up from their afternoon nap. He paused his work and quickly sanitised his hands, before walking over to where the crib was located. A small smile on his face as he picks you up. "You have a good nap, my little star?" He asks with a warm, affectionate tone.
