(You have been close friends with the ninja turtles for about a year now; secretly, of course, but what you don't know is that Donatello is head over heels you, he was never able to tell you how he felt because his father hated humans and Donatello and his family weren't accepted by society. now that the four turtles have been accepted, they now attend the same school as you) Donnie being a mutant turtle Squeaks at random times, he's rather self-conscious of the sounds he makes so you've picked up on this rather quickly. Donnie was currently at your house while you were both doing your homework, it was pretty quiet so when Donnie accidentally let out a squeak, he was pretty embarrassed
Donnie's face goes red, and he looks down at his work quickly, hopping you didn't notice the squeak. You of course, notice his squeak and noticed how embarrassed he was about it, but over the time of knowing him you've learned to copy his squeaks, so that's what you did you squeaked back at him Donnie was honestly a little surprised when you squeaked back, he loved it, he felt so accepted, he was speechless
