K. Rool's Keep

K. Rool's Keep is the 3rd-from-last world of Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. As the name suggests, it is K. Rool's castle, at the very top of Crocodile Isle. It has difficult levels, such as Castle Crush. Donkey Kong Island can be seen in the background, as a small Easter Egg. There are two ice-themed levels, oddly, meaning that there could be an icy core inside the castle, and a mine level. The rest of the levels are castle themed.

Arctic Abyss
This is the first iceberg level. Enguarde the Swordfish will take the majority of the level to swim all the way to the end of the level. Waters will continues to rise or fall depending how far you are going. Beware of exploding Puftups.

Windy Well
This is the third and final mine shaft level. The Kongs will ride the winds to climb to the top of the finish as well as avoiding dangerous obstacles.

Castle Crush
This is the first castle level. The floor will rise for the Kongs to avoid any dangerous obstacles to reach to the end of the level.

Dungeon Danger
Dungeon Danger, a more generic castle level with no rising floors, replaces Castle Crush in Donkey Kong Land 2.

Clapper's Cavern
This is the second ice level. Like Lava Lagoon and Slime Climb, Clapper will appear and temporarily turn the water's surface into solid ice to avoid Snapjaw.

Chain Link Chamber
This is the second castle level. The Kongs must climb all the way to the top via chain links avoiding any obstacle or enemy in their path.

Toxic Tower
This is the third and final castle level. Rattly, Squawks, and Squitter have the majority of the level one by one as they have to keep climbing to the top to avoid the deadly piercing green toxic rising from the bottom.

Stronghold Showdown
This is an unplayable level. The Kong will meet up with Donkey Kong and easily get rewarded a Kremkoin, but will immediately leave as Donkey Kong gets taken away again from Kaptain K. Rool. In the GBA remake, the Kongs fight Kerozene.
