Brutus turns Wimpy into a colossal man. Wimpy eats "grow pills" and becomes a Paul Bunyan-like freak in a carnival. The Sea Hag also gets involved in the diabolical plot. Brutus, the carnival owner, cannot make money on Wimpy- he eats too many hamburgers. Brutus finally leaves Wimpy in Popeye's care. Popeye, with the help of Swee'Pea and Swee'Pea's chemistry set, invent a reducing pill to bring Wimpy back to normal.
