Every giant needs his five a day, but Brian loves to watch "humunchies" trying hard to please him by feeding him the most meatballs and sprouts. Doing their best and fighting for freedom are the Loopy Leopards from Newcastle-under-Lyme and the Brainiacs from London. Every giant's favourite game show host, Les Dennis, is also trapped in the studio, and there is nothing he can do to save the losing team from ending up as Brian's dinner.
