Bilbo is a fan of comic books. His favourite film is "Hawk the Slayer" and he has been known to turn violent if it's insulted, once punching his own father in the face. He is the manager of Fantasy Bazaar, a comic book store, where he employs Tim as his assistant manager.
He made his final appearance during "Change", in which he fired Tim for insulting a boy who had saved up his 50 pence pieces to buy a Jar Jar Binks doll from Star Wars: Episode 1 - The Phantom Menace, a film that Tim despised. Tim went to work for a rival comic book store operated by Derek, whom Bilbo disliked, and Bilbo hired a Tim lookalike. Bilbo later regretted his decision, and re-hired Tim.
