He was a green anthropomorphic sprinkle with two arms and two legs. He doesn't seem to have any eyes. He was extremely small, and was around the same height as CreamBob's shoes.
CreamBob ConePants introduced him, along with the other main ice cream characters, to SpongeBob and Patrick. It is then implied that he, along with everyone else in Pint Bottom, was eaten by SpongeBob and Patrick.
