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 Donkey Kong Land 2. It is also the fourth area of K. Rool's Keep. It should be noted that it was moved to the third area in the Game Boy Advance remake of Diddy's Kong Quest.

This icy level shares some similarities with 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. However, if they're not fast enough, the water will melt, and the Kongs will fall into the water with the hungry foe. Enguarde also appears in a short area without the Snapjaw. In Donkey Kong Land 2, Snapjaws do not appear, and instead, the water can hurt a monkey with one touch, thus making the level a bit trickier. The helpful swordfish Animal Buddy is also not present in the pseudo-sequel. Enemies here include Klampons, Krunchas, Neeks, Spinys, Zingers, Click-Clacks, Flitters, Shuries, Floatsams and Puftups, including the Snapjaw, exclusive to Donkey Kong Country 2.

Donkey Kong Country 2
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 heroes 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 Animal Sign 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 group needs 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 group 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.

Donkey Kong Land 2
When they begin the level, the heroes must travel east and jump on Clapper. After he freezes the water, they need to run across, but before it melts, to avoid the hungry Snapjaw below. After going up and under a few Zingers, they will get to land again and defeat a lone Spiny. Afterwards, they must bounce off of another Clapper, and freeze the water. Once they slide under two Zingers, the Kongs need to hurry back on the solid ground. But they can still not dawdle, because they must quickly cross more ice before it cools down. Soon, though, they should be able to reach safety, and simply walk along the solid path. They'll meet a few enemies on the way, and also have to jump over two abysses. But, the group will eventually come up to the next Clapper. After he cools down the liquid, they need to dash over the ice. They must jump over and slide under a few more Zingers here, but soon get back on the safe surface. Here, they will find the Star Barrel.

From there, the heroes must hop on top of Clapper and race over the slippery ice. Once they pass the Zinger over this icy water, they will have to continue running over the safe ground, until they find another frozen section of water. Before it melts, they have to run and dodge more enemies. Again, they will finally make it back on land, but have to cross more ice. Hopefully, if it hasn't turned back into it's liquid form, the Kongs should be able to cross it, and finally be back on the safe ground. After all that, the heroes must simply leap over a few abysses and avoid some enemies, including the mighty Kruncha foe, who won't give up just from a single hit given by the monkeys. Eventually, the group will meet another Clapper. Once they jump on him, they must, as usual, dash across the slippery ice. This time across, there are several Zingers in the path, and they need to hop over or slip under each one. Once back on land, the heroes should watch out for a Kruncha, and jump over a rather large gap. After that, they will find a spring, and it will take them out 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 Kremkoin, 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 Kremkoin 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.

Bonus Level(s)
After the Star Barrel, the monkeys should come up to the second ice path after it. When they jump down to the ice, Dixie Kong must flutter through the air and bounce off of a Flitter. Then, she and Diddy will land into the Bonus Barrel. It it's Bonus Level, the heroes need to jump platform-to-platform and dodge a few Klampons. Once they get to the end, they can obtain the Kremkoin.

DK Coin
At the beginning of the level, the Kongs should walk backwards. They should look for a hidden hook, and cling onto it to reach a barrel above them. It will shoot them to several other barrels, and soon to the DK Coin.
