Seal

Seal is a seal dressed in a pirate outfit that appears in Donkey Kong 64. He is first seen in Gloomy Galleon, where he is locked in a prison near the Lighthouse. Donkey Kong must finish Gloomy Galleom's Baboon Blast in order to free Seal and obtain a Golden Banana. He then challenges him in a boat race for another Golden Banana. He is seen again during the ending sequence in the water near DK's Treehouse, and two other seals that looks exactly like Seal appears during the intro sequence swimming around Donkey Kong Island. He is also similar in appearance to Clapper the Seal, from Donkey Kong Country 2: Diddy's Kong Quest.
