In "Lotsa Luck," Donald falls overboard during a South Sea cruise while holding the "lucky buck" -- the supposed source of Cousin Gladstone's famed luck. Next, in "The Letter Mouse Trap," Goofy mysteriously disappears, leaving only a letter and a wooden crate behind. The resulting trail of trouble leads Mickey all around the world -- and into the clutches of a robot army! Finally, in "Crash Course," Scrooge vies with John D. Rockerduck to see whose factory builds the safest car. The competition calls for driving two crazily souped-up models through gut-grindingly treacherous mountain passes!
