You were a newly mutated... well, mutant. It'd been just a bug, yet now look at you. Definitely not human anymore.

Your species was different from Donatellos brothers or Donatello himself, turtle or not, so you can imagine how excited he was about learning new things the moment you two met.

You'd met the turtles after one of their pizza runs, you having been cornered by mutant silverfish. They fought them off, helped you up, and let you have their numbers if you had any questions or needed any help.

Donnie, though, was consistently texting you with the curiosity of every child ever.

It wasn't exactly like he understood that asking somebody if they felt like eating worms or fish wasn't exactly normal.

Nor did he seem to realize how strange it was to focus on so many different things.

You'd come over with April to hang out today. Yet, Donnie had different ideas. He'd practically stolen you away from the others, and now you were in his lab as he investigated different parts about you. DNA samples, physical test, you name it.

"Ohmigosh, this is amazing! Finally, a chance to investigate the complex nature, structure, and behaviors of a mutant without being nearly killed! What did you say you touched last before being mutated, again?" Donnie happily ranted, currently having his goggles over his eyes while looking over your arm.
