K. Lumsy Island is a small, cave-like island that the giant Kremling K. Lumsy is locked up in for most of Donkey Kong 64. The cell K. Lumsy is kept in features locks that require keys dropped from the boss of each world in order to open.
- When compared with K. Lumsy, the island is considerably smaller than he is. This is obviously an error in-game that the editors never got around to fixing.
