Clapper's Cavern (Donkey Kong Country 2: Diddy's Kong Quest)

Clapper's Cavern is the thirty-first level of Donkey Kong Country 2: Diddy's Kong Quest, and the fourth area of K. Rool's Keep.

This icy level share some similarities to Slime Climb, as the water rises, and a Snapjaw is after the Kongs. Since the Kongs cannot safely enter the water, Clapper returns from Lava Lagoon. This time however, Clapper will briefly freeze the water, trapping the Snapjaw under the ice so that the Kongs can walk across it. Enguarde also appears in an area without the Snapjaw. Other enemies here include Klampons, Krunchas, Neeks, Spinys, Zingers, Click-Clacks, Flitters, Shuries, Floatsams and Puftups.

Gameplay
At the start of the level, the Kongs must travel east where they meet Clapper the Seal. They then need to jump on him, and Clapper will cool down the water so they can walk on it, avoiding the Snapjaw below them. Quickly, the two monkeys must run across the ice, jumping over Zingers, before it warms up and becomes a liquid. Once back on land, the Kongs will avoid a few enemies and jump on another Clapper, who will freeze the water again. As they run across the ice again, there will be a few Neeks and some Zingers to jump over. Afterward, the Kongs must walk into the nearby barrel that will shoot them up to a higher part of the level. From there, the monkeys need to travel west and jump across two small gaps, then jumping on the third Clapper,who will cool the water down. At that point, they must jump over a group of two Zingers and also slide under another Zinger. There will be a barrel the the Kongs must go in. It will shoot them up to an even higher area of the level, where they can get on Enguarde, the Animal Buddy. With the swordfish, they can ride up north through the water and shortly after, pass a "No Enguarde" sign, making then lose their Animal Buddy, and exit the water alone. Diddy and Dixie then need to jump across a rather small gap and break the Star Barrel.

Halfway through the level, the Kongs need to jump on a Clapper and run across the ice again. There, they will have to fight or avoid many enemies such as Neeks and Zingers. Once they reach land, they need to carefully avoid some enemies and hop on the chains to reach the highest part of the level. Here, the monkyes must jump across a gap and land on a Clapper, freezing the water yet again. When running across the solid ice, Diddy and Dixie will avoid some enemies and even slide under three Zingers, then quickly jump on another Clapper. Still on the ice, they will jump over or slide under many Zingers until they come to the end of the level.

Bonus Levels
From the very start, Diddy and Dixie must use their Team-up move to throw a monkey in the air. A hidden chain will appear to climb up on, and the Kongs will have to go up slightly higher until they reach the top. There, they must avoid a few enemies and enter a small door, leading to the first bonus level. Here, the monkeys will simply have to climb to slippery platforms until they get to the coin, completing the first Bonus Level.

The second Bonus Level is underwater in a hidden cave. To get there, the two Kongs must get on Enguarde and travel around in the cold water until they see a wall with a banana next to it. Using Enguarde's special move, they can break the wall open and enter the next Bonus Level. In the level, the monkeys will still be on Enguarde and have to reach the coin before time runs out. The water level will decrease, so the swordfish and the two monkeys must quickly move forward. If the water drains before the Kongs reach the coin, Enguarde will not be able to move fast, as he can only move in water, thus running the clock and running out of time. If the Kongs make the fish use his special move, he can move much faster, and make it to the coin before time runs out.

DK Coin
To get the DK Coin, the Kongs must go where the exit of the first Bonus Level is. From there, they need to use their Team-up move. A hidden chain should appear, and the DK Coin is right above it. The Kongs must simply jump up and grab the coin.

Golden Feather (GBA Only)
The Golden Feather is not far from the location of the DK Coin. From where that coin is, the monkeys should move slightly east and do the Team-up move. If they are standing in the right spot, the one monkey will be thrown right into the feather and grab it.
