Raphael, Donatello, And Leo would be on the rooftop waiting for Michelangelo.

Michelangelo: he’d be wearing a raincoat and a top hat to pretend to be human and blend in. He’d walk into the store to buy pizza for the others, but the hat knocks off and then out of panic he would try to pick it up. In the process, the raincoat would also fall, revealing his real turtle body to you. Uhh…

Leo: Damn it! Mikey got caught!
