Wally is having trouble trying to find a fifth person to go to the new amusement park in Bellport on their five person entrance discount. It seems that most of his friends already have groups of five. So Wally ends up choosing as his fifth who he considers the last resort, Beaver, if only because Wally's friends wouldn't consider hanging around with Beaver as fun. After the tickets have been purchased, Richard and Whitey tell Beaver that the scariest roller coaster they've heard of, called the Big Dipper, is at this amusement park. Beaver doesn't want to admit to anyone that he's afraid of the thought of such a ride, especially to his own friends, and Wally and Wally's "big guy" friends. After talking to Gus, Beaver thinks he has overcome the thought of his fear. But will that thought actually translate into reality when Beaver sees the Big Dipper itself?
