He's an immature and bratty man-child with a short temper, as he never got to properly grow up. Despite his childishness, Arlo smokes, drinks, and swears profusely. This means that Arlo is shockingly impulsive and self- absorbed. As Mr. Marble, Arlo wears a bright blue bobbed wig, white contact lenses that sometimes give him the appearance of having no irises whatsoever, and a uniform consisting of a lilac crown- hat, a bright pink suit, and a blue, sequined shirt.
