At the carnival talent show the day before the race, the boys try to fund-raise $450, the cost of the lumber needed to rebuild their clubhouse. The youngest club members, Buckwheat and Porky, have unwittingly come up with $500, not realizing that their method for earning the money was not exactly honest. Their school teacher, Miss Crabtree, finds out about the scheme and confronts Spanky, but he convinces her to donate the money to be given as first prize in the go-kart derby.
