A spawn of Satan appears in the episode "Puppy Sitter." He is the subject of a mission Annabelle assigns to Charlie and Itchy Itchiford. Charlie, intending to use the puppy just to impress Satan, misses the fact that the puppy really wants to eat him, even when he smears ketchup and mustard all over Charlie's body. "Puppy" is the only name Charlie has for him, as he doesn't know his demon name. In fact, it's never revealed, not even by Satan.
