He is described as being shorter than Miss Mush. Most of his toes are approximately one and a half inches long, his feet are nine inches long, his arms are two and a half feet long each, his palms are four inches long, and his longest finger is three inches.
Although little is known about him since he only appears once in the entire series, a fair amount of information is given about him. Often, Miss Mush will pull playful pranks on him, since he's much shorter. Often he laughs along, partially because he is a good sport, and partially because Miss Mush is his boss and he doesn't want to get fired.
