Ep 40. The Gang's All Here

Bebop and Rocksteady put on an act to get the Turtles to eat cookies, but not any ordinary cookies, because these cookies could turn them into humans! Tempted to find out what being a human is like, Michelangelo eats one and becomes one. While the effects wears off from time to time, they still kick back in. Meanwhile, the Turtles search for Michelangelo with an antidote for the anti-mutagen before it destroys him, while Shredder's two mutant goons ask for help from their old gang to rob a ship. And during it all, April attempts to "join" the gang to get a story for Burne.
