The main characters are Wallace and Gromit, whose new company, Anti-Pesto, is charged with keeping rabbits away from the upcoming Giant Vegetable Competition, which has been run by Lady Tottington's family at Tottington Hall for 517 years. Gromit can visit Mr. Caliche's shop, where he can purchase items to help grow the marrow that he's preparing for the Giant Vegetable Competition. As the duo progress through the game, a fortune teller, Madame Winnie Bago, who befriended Wallace and Gromit after they fixed her van, offers them tips and hints to help them complete tasks successfully.
