Kremkroc Industries, Inc.

Kremkroc Industries, Inc., formatted as Kremkroc Industries in the Game Boy Color version and also known as Kremkrock Industry Inc., is the fifth world in Donkey Kong Country. Located at the top-left of Donkey Kong Island, Kremkroc Industries, Inc. is an industrial area filled with subterranean areas and factories run by the Kremlings. The factories generate a lot of pollution, causing the area to be murky. The pollution even carries over into a large pond at the bottom of the world. According to the Nintendo Power guide, Kremkroc Industries, Inc. used to be a lush environment before Kremlings built the factories. The world's boss is Dumb Drum, who is a large black drum. The Factory world from Donkey Kong Country Returns is thematically similar and contains arrangements of its music; it has been suggested to be the same location.

In the Donkey Kong Country TV show, the place appears as King K. Rool's lair which the Mines are connected to.
