Clapper

Clapper, also formatted as Klapper, is an Animal Friend who appears in Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, in the levels Lava Lagoon and Clapper's Cavern. A character resembling Clapper, named Seal, later appears in Donkey Kong 64. Clapper reappears in the Freestyle Mode in Donkey Konga 2.

Clapper got his name from the popular depiction of seals clapping with their flippers, which he himself does in the games. He has silver fur, large eyes, and a tan snout with a black nose and five whiskers on each side.

Description
Clapper always sits next to a body of water stationary, and he has the ability to cool the water temperature. To do so, Diddy and Dixie Kong must jump on Clapper, who breathes into the water and then claps his flippers (hence his name). In Lava Lagoon, Clapper cools down the boiling lava water, allowing Diddy and Dixie Kong to safely swim through. In Clapper's Cavern, a level bearing his name, Clapper freezes the water into solid ice, allowing the Kongs to safely cross above Snapjaw.

After a while, the water that Clapper had cooled changes back into its original temperature; therefore the Kongs should quickly move through the level. Since the water temperature only changes temporarily, Clapper appears a few times throughout both Lava Lagoon and Clapper's Cavern to compensate. Clapper is the only Animal Friend in the game who does not have his own Animal Crate.
