His perverted nature causes him to be suspended from school often. He wears black pants that go only to his knees and his signature hat. Under that is a white dress shirt with a skinny black tie. His school uniform consists of the black uniform jacket over a red jacket that has fur bordering the hood. He wears this with black pants and his signature fedora hat.
