The exterior of K. Lumsy's Island as seen in the game Donkey Kong 64 for Nintendo 64.

K. Lumsy's Island is a small, cave-like island towed by King K. Rool's Mobile Island Fortress in the game Donkey Kong 64. This small island is where the giant Kremling K. Lumsy, K. Rool's younger brother, is locked up in for most of the game.


K. Lumsy was imprisoned for refusing to follow his brother's command and destroy the DK Island. The cage where the giant is kept in features eight numbered locks. In order to be open, these locks require Boss Keys usually dropped after bosses are defeated in each level of the game.

As soon as the player collects one or more Boss Keys, they must return to the island and approach the locks to use the keys. In these occasions, K. Lumsy will celebrate by violently dancing and jumping inside his cage. The celebration will usually reveal new paths to access new levels and locations in the game.



  • When comparing dimensions between exterior and interior views of the island, and also taking in account K. Lumsy's size, the interior is too big to be contained inside the structure.
