Jello of Justice

The Jello of Justice is an indestructible cube-ish mass of lime-flavored gelatin with chunks of fruit for a brain. He is a resident of Metropia and an ally of Super Root Beer Man, and is smarter than he looks (or acts). His malleability makes him useful for sneaking into evil lairs, and while he is very difficult for villains to destroy, he also can't do a whole lot of damage, being mostly water.
