He looks similar to Mr. Krabs, but has a curly black mustache, lacks a nose, and wears no clothing. However, he is shown in a black-and-white turtleneck following his arrest.
Role in episode
He is shown stealing a sleeping hermit crab's shell to use for himself. The victim then wakes up and points to where the thief went so the police can arrest him.
They are successful in arresting the criminal, but he deems his arrest unfair. Mr. Krabs then complains about how he hates when people steal things like the crab did on the show, before SpongeBob and Patrick point out his hypocrisy by stating the many things he himself has stolen.
