Hot Dog Guy is somewhat level-headed but not very willing to come out of his comfort zone, as seen in " The Cringe" when he refuses to shower naked with Gumball, wearing swimming trunks instead. Hot Dog Guy is an ordinary enough person but does not deal well in awkward situations, to the point that he and Gumball have had to block out some of their awkward memories together. Prior to " The Extras," he did not have a mouth. As of " The Hug," he wears a wig resembling a tuft of mustard to hide the birth scar on his head. He is always seen wearing a pair of dark sunglasses. He is a large anthropomorphic hot dog, with very thin arms and legs.
