K. Rool's Keep
As its name suggests, K. Rool's Keep belongs to Kaptain K. Rool. Since the area is at a high elevation, some surrounding areas are entirely frozen and constantly battered by high winds. The castle is hazardous to climb, as there are two ice caverns, a mine shaft, and three dungeons between the bottom and top of the castle. Every dungeon-based level has a quirk to impede Diddy and Dixie Kong's progress; the first dungeon has a rising floor, meaning the heroes could get crushed if they do not move out of the way of the ceiling quick enough. The only way to proceed up the second dungeon is by climbing chain links, guarded by a plethora of enemies and obstacles. The third dungeon has a rising pool of toxic waste. Donkey Kong Island also appears in the background, on the left side of the world map.
Unlike the other worlds in the Super Nintendo version, K. Rool's Keep does not have a boss. However, it eventually received its own boss in the Game Boy Advance remake: a large, orange monster named Kerozene.
In the Game Boy Advance remake of Donkey Kong Country 2, the castle was remodeled to look like a cylindrical medieval tower, in addition to giving the bottom of the castle a floor of ice. Furthermore, there is snow outside at the world's Kong Kollege. Donkey Kong Island can no longer be seen from the world map.
In the ending of both Donkey Kong Country 2 and Donkey Kong Land 2, after the Lost World explodes, the entire Crocodile Isle sinks into the ocean, including K. Rool's Keep.
Castle Crush is absent from Donkey Kong Land 2 and is replaced with a different level, Dungeon Danger. In the Game Boy Advance release, the level order is slightly different: Castle Crush is the second level, Clapper's Cavern is the third, and Windy Well is the fourth.
