Clapper is a seal who first debuted in the classic SNES game Donkey Kong Country. He then appeared in Donkey Kong Country 2: Diddy's Kong Quest, and then in a pirate form in the Nintendo 64 game, Donkey Kong 64. Clapper could either make the water cool enough so the player could swim in it, or unfreeze ice so the player could swim in it. You had to jump on him for it to work.
Clapper appears as one of the aquatic animal buddies in the Wii racing game, Donkey Kong Racing. Clapper is strong, but slow, with high Stamina. Clapper's attack is to spew out lava, which depletes stamina from the victim.
