Justice League Unlimited Season 1 Episode 3 Kids' Stuff Episode Title:Kids' Stuff.Episode Description:Morgaine le Fey transforms Superman, Batman, Wonder Woman, and Green Lantern into 8-year-olds after Mordred uses his magic to remove all adults from Earth and keep children on the earth. Lots of comic relief in this episode comes from Wonder Girl displaying a crush on Batboy, who simply acts like a smaller version of his adult self, a clueless Superboy in every situation, a young Green Lantern who hides his nerdish side, and the Demon Etrigan as an infant. Based loosely on elements of the DC Comics events JLA: World Without Grown Ups and Young Justice: Sins of Youth.[citation needed]
