Krocodile Kore

Krocodile Kore is the location of the final boss of Donkey Kong Country 2: Diddy's Kong Quest, Kaptain K. Rool. It is the "final" level of Lost World, unlocked by accessing and beating all the other levels in Lost World.

Location
After beating every level in Lost World, the strange Kremling-shaped volcano in the middle of Lost World will open it's mouth, revealing the entrance to Krocodile Kore. Krocodile Kore itself is an odd shrine-like area with old Kremling relics and a very mysterious geyser that pumps odd blue and pink energy that somehow powers Crocodile Isle.

Battle
Upon entering the Kore, Kaptain K. Rool's battle theme from the end of The Flying Krock plays, signifying his return. How he survived a vicious shark attack is unknown, however when the battle starts he will be drenched, and have seaweed and a fish or two shaken off. The Kongs will battle him once again, however this time, he will fire a very long onslaught of spiked Kannonballs and odd energy projectiles, without breaks to toss a kannonball into his gun. Only after the onslaught will he fire a Wooden Barrel, and the Kongs can break it for the Kannonball.

After throwing the kannonball into K. Rool's gun again, he will explode off into the geyser and there will suddenly be an earthquake. Sparks will fly from the strange geyser and the Kongs escape. They will get a different ending this time, this one showing Crocodile Isle exploding.

It was later resurrected along with the rest of the island in Donkey Kong Land 2. This time around, the geyser no longer pumped energy, but was sunk down again anyway.
