Foop resembles Poof, but he is shaped like a cube rather than a sphere. He also was born with a black mustache and goatee on his face, the kind typically seen on stereotypical villains or drawn on pictures as vandalism. It is interesting to note a goatee on a doppelganger insinuates its the evil one. His pajamas are slightly darker blue than his skin, and they have a skull symbol on them. Foop has bat wings and a black crown like all Anti-Fairies. His wand is a baby bottle with blue bat wings on the side, as opposed to Poof's baby rattle. He also speaks with a stereotypical British gentleman's accent like his father Anti-Cosmo, who apparently grew to dislike him soon after his birth. Foop's tears are also made of acid. He inherited the same set of fangs and pointed ears from his father, and has the same eyebrows and eyelashes his mother has.
