A sponge which is shapes sort of like a lump with little nubs for arms and little feet, two derpy eyes, and a small mouth, he's used for cleaning and can hold water, the more water he holds the bigger and fatter he gets, if you squeeze him or wring him out he becomes empty and small again, he's very stupid but friendly, he can also absorb other liquids, and can be used to clean things like dishes, he's basically a living sponge monster
