Garfield (character) is awakened early in the morning by the obnoxious ''Binky the Clown Show'' and learns that it is Halloween, becoming excited about trick-or-treating. He tricks Odie into thinking dogs are required to trick-or-treat with cats and give almost all of their candy to them, save one piece of candy for the dog. Odie is tempted by the minimal reward, and the two head for the attic to find costumes in an old trunk. After considering a number of options, Garfield decides he and Odie will be pirates.
