Oysters, also called Klams, are enemies that appear in Donkey Kong 64.
These large, clam-like enemies are only found in Gloomy Galleon inside of a large treasure chest that only Tiny Kong can get into. There are several Oysters located in the treasure chest and each of them has a pearl that belongs to the Mermaid. Tiny must retrieve the pearls from the Oysters when they open their mouths. Tiny must also be careful not to get chomped on as their teeth is damaging.
