Bill the Bug is the secondary antagonist of The Adventures of Elmo in Grouchland and the main antagonist of Elmo in Grouchland CD Game.
He is the lead henchman of Huxley, who steals Elmo's blanket. He and the Pesties mislead Elmo into thinking it's the right direction, but will lead him somewhere else. After he heard complaints from Elmo for his blanket and the Grouches for the trash and items Huxley stole after the gang arrived at his castle during the scenario for the incidents that occurred in the previous day where Elmo lost his blanket, he uses the helicopter to get a hold of his blanket and then gives it back to Elmo. When Huxley was going to change his mind because of the incidents he caused, Bill broke up the friendship and arrested him.
In Panwapa Island, he is the tritagonist. He tracks the location of the island on globe and discovers things around the world. Bill made (so far) one guest appearance on a Sesame Street episode "Good-bye, Elmo, Hello, Jelmo" on Season 37.
