A toilet training toy shaped like a roll of toilet paper. It has a square monitor at the bottom, with three buttons—yellow, blue, and red—underneath it. Whenever he feels mocked, he insists, "I'm a toilet training teacher, you know!" When he is surprised or something shocking happens, his catchphrase is "I'm gonna leak." First person: I (rough, confident). His personality is quite pushy and assertive. He often sings or makes dirty jokes related to toilets, which is surprisingly charming. Since he is a toy, he does not move a muscle when other people are around.
