Clapper

Clapper the Seal is an Animal Buddy in the Donkey Kong series who first appeared in Donkey Kong Country 2: Diddy's Kong Quest.

Donkey Kong Country 2: Diddy's Kong Quest/Donkey Kong Land 2
In Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, Clapper can cool down or freeze water with his breath if the Kongs jump on him; this allows the Kongs to swim past boiling parts of water or to walk on top of the ice.

Levels: Clapper appears in both versions unless otherwise noted.
 * Lava Lagoon
 * Clapper's Cavern

Donkey Kong 64
A seal nearly identical to Clapper in Donkey Kong 64's fourth world is dressed like a pirate and can communicate with the Kongs (unlike Clapper).

Levels:
 * Gloomy Galleon

Trivia

 * Clapper got his name from the fact that seals constantly clap when they laugh.
 * Clapper is one of few of the Animal Buddies that tends to appear several times in a level.
