Arctic Abyss is the twenty-eighth level of Donkey Kong Country 2: Diddy's Kong Quest, and the first area of K. Rool's Keep.
The first area in K. Rool's Keep is also the first icy level (outside the Lost World). Much of this level is flooded, although thanks to an Animal Barrel, Enguarde is around to get through the bulk of it. Expect to find Kabooms, Floatsams, Shuries, Lockjaws and even Zingers here as well.
