In one of the best "Treehouse of Horror" episodes, it's revealed that Bart has an evil twin brother living in the attic of the house. What is his twin's name?

In "Treehouse of Horror VII," Bart, Lisa, and Maggie hear strange sounds from the attic and discover Hugo living up there. In preparation for being reattached to Bart, Hugo tells them he's made a "Pigeon-Rat". As the episode progresses, the family realizes that Bart is actually the evil twin, so he gets sent to the attic, where he's fed fish heads.
