In keeping with the various animation styles that form for the various characters, Wooldoor and Toot have four fingers on each hand, whereas Clara, Foxxy, Hero, and Xandir have five. In promotional artwork for the show, Toot and Wooldoor are drawn with the standard five fingers, but in the show itself they have four. Also, whereas most of the characters are drawn with black outlines, Clara and items belonging to her are drawn with soft edges, a reference to Disney animation techniques, which involve "cleanup" of any black outlines.
