A troll is seen working for Knut alongside the ghouls in the first episode as they attempt to kill Bloom and steal Stella's scepter. He throws Stella out the window, but is defeated by Timmy, who takes out his feet and sends him falling into a crevice. Afterward he is captured by the specialists, but as he is being transferred in The Voice of Nature, the Trix break him out to prevent him from revealing their plan to the authorities. Once they get the troll to come to them, the Trix imprison him in limbo.
