I’m a huge sucker for the whole headcanon of Donnie using his own form of ASL especially when he was younger, I made this tot comic a few months back and felt like it deserved to be inked.
bonus for after he turned back to normal:
I like the idea that Raph taught him when it became a communication problem, and Mikey noticed this for the first time when they were turned into tots (since Mikey was literally a baby when it happened originally), so he had to break out Raph’s “How to be a Big Brother like a Boss” book (from the og ToddlerMNT storyboards hehe) to figure out how to help. :,)
also I know DAMN well that Mikey didn’t know this as a child and genuinely through Donnie just couldn’t hear him.
Poor baby doesn’t know anything he’s just three apples tall he doesn’t know any better 😭😭
( the sign btw is their two hands put together)
