The Whistling Choir Death Match Championship is an event in the Land of Ooo that apparently involves participants whistling. While its name implies that it is deadly, this cannot be known for certain, as the tournament was never shown. Princess Bubblegum apparently competes in this competition, as seen in "Go With Me" when she was seen practicing for it.
