Jimmy Roberts (Dominic Janes) is a 12-year-old boy who can't seem to say no to anybody, and as a result, ends up getting taken advantage of on a regular basis, even by his best friend Craig (Micah Karns). This problem continues during his class trip to Gollyworld, where he misses out on many of the rides because Craig tells the popular kids that Jimmy will hold their items for them. The popular kids then, on Craig's suggestion, tell Jimmy to go try to find Milt Appleday's (Fred Willard) frozen brain, which supposedly is hidden somewhere in Tux's Arctic Adventure. As usual, Jimmy unwillingly gives in, and once there, bumps into Milt's son Sonny (Matt Knudsen), who is attempting to retrieve the brain from underneath the ice. After being spotted by Sonny, Jimmy quickly flees and during his escape, accidentally runs onto the path of an oncoming train and is sent to the hospital, where Milt's brain (which one of the doctors keeps in his lunch cooler) is transplanted into his head. He makes it out of the operation just fine with his personality intact (explained by the doctors salvaging his "personality gland") but, he can now see all of Appleday's characters in real life, while no one else can.
