Roulette Barrels are objects appearing as the main focus of the "Stop the Barrel!" Bonus Stages in Donkey Kong Country and its reissues. Depending on the exact challenge, they act slightly different, but always hover in the air in groups and are used to collect items. Some switch between items in a slot machine style and need to be stopped on a matching item to win; a variation of this uses K-O-N-G Letters that need stopped in the position that spells the word properly. A different type has a single item, usually a Donkey Kong Balloon, rapidly moving between barrels in a shell game-like fashion before stopping and disappearing; to gain the item, the player needs to select the one it stopped on. In the Game Boy Color remake, some of this type appear in one of Candy's Challenges.
