I just had a thought okay so whenever we pick up a turtle at work and end up holding it like this:
we'll talk in a baby voice and call the turtle some type of sandwich ("hi hamburger" "oh arent you just a little meatball sub!") before pretending we're gonna eat them because its funny
So the thought is Splinter picking up the boys when they were little like this, and pretending he's gonna eat them just to mess with them. Theyd wiggle and squeal and call it the hamburger game. One day April randomly hands Casey Jr a baby and he starts playing the hamburger game to entertain the kid, because thats how his turtle uncles played with him until he got too big to pick up 🥹
