Arctic Abyss (Donkey Kong Country 2: Diddy's Kong Quest)

Arctic Abyss is the twenty-eighth level of Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. It is also 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) in the game. Much of this level is flooded, although thanks to an Animal Barrel, Enguarde is around to get through the bulk of it. Even though the water is cold, the Animal Buddy is able to swim through and hurry about the area, before the water level decreases. If he is unable to get somewhere by the time the water goes down though, Enguarde will not have to ability to get it back up and collect special items. Enemies here include Kabooms, Floatsams, Shuries, Lockjaws and even Zingers, who will try to attack the Kongs and their swordfish friend.

Bonus Level(s)
Once the Kongs plunge into the water after the Star Barrel, they should look around the wall to the left. They will squeeze into a small space and have to defeat a few enemies. When they reach the dead end, they must swim right up to the wall, where they'll find the hidden Bonus Barrel. In it's Bonus Level, the monkeys must swim through the area, avoiding foes, such as Flotsams, until they get to the end, where the Kremkoin is.

Just before the No Animal Sign, the Kongs must float down and spy another small opening on the left wall. They should swim through here and defeat enemies, until they get to the Bonus Barrel, leading to the Bonus Level. Here, they need to collect several stars (which are in the formation of the letters, DK), and then swim to the bottom-center of the area to claim their Kremkoin. Time is short, so they must swim quickly.

DK Coin
Before dipping into the water after the Star Barrel, the Kongs will see a high ledge to the right. They should jump up there and walk along the ice, until they find the DK Coin.
