The UFO parts will be scattered around town after the player accepts Gulliver's plead to find them; five parts are needed to complete the task. After the player collects all five of them and talk to Gulliver, he will give them a rare furniture that isn't obtainable via Tom Nook's shop (the furniture is listed in UFO). If they has UFO Parts and doesn't give them to Gulliver after a day passes, Gulliver will go away. The UFO Parts are worth 0 Bells when sold to Tom Nook, and can be kept until Gulliver reappears.
