Huey, Dewey, and Louie ask Donald some help for a scavenger hunt contest where everybody gets a different list. Donald is uninterested until he hears the prize is fifty dollars, so he decides to participate too. On their way there, they find Gladstone Gander is also participating.
Donald arrives just in time to get a list for himself and another for his nephews. Donald's list includes a parrot feather, a brown cow and an otter, so a farmer friend gives him a chicken feather, a white cow and a cat, and Donald paints them.
Huey, Dewey, and Louie already have false teeth and a professor's glasses, and get a wooden leg from a mariner. While they check they only need a goat, Gladstone passes them rollerskating with all the items of his list. The kids hurry to get a goat that follows them, but they manage to ride on its back and drive it to the finish point.
Donald and Gladstone arrive at the same time, and the kids come late for just a little. The winner is decided by picking straws and Donald gets the long straw, but it rains and the paint comes off the feather, cow and cat. This makes Gladstone the winner, until it turns one of his items, a monkey, was stolen from his owner. Even though Gladstone claims he was going to return it, he is disqualified for taking it without asking. Therefore, the winners are Huey, Dewey, and Louie.
Donald asks his nephews what are they going to do with the money. It turns they go to a roller coaster, and while Donald is scared, his nephews remember he always tells to ignore the backseat passenger.
