While stuck cleaning the house, Bart wins a radio contest and chooses a gag prize, an elephant, instead of the real prize, $10,000 cash. The radio station eventually gets Bart his elephant, which is named Stampy. When taking care of Stampy gets too expensive Homer decides to sell him to an ivory dealer rather than turn him over to a non-profit Animal Refuge. Bart tries to run away with Stampy, but the elephant escapes. They track him down, and Homer agrees to give him to the Animal Refuge.
