From the Super Mario Wiki
Krem Cauldron is the second world of Donkey Kong Land 2. It is a combination of the Krem Quay and Crocodile Cauldron worlds from Donkey Kong Country 2: Diddy's Kong Quest. Even its name combines a word from each world. The world's boss is Kleaver, who is fought at the end.
The area features ten levels, five from Crocodile Cauldron and five from Krem Quay. Krem Cauldron is the world with the most levels in the game.
Diddy and Dixie Kong go through Krem Cauldron starting at the right and slowly making their way left. The right half of Krem Cauldron is volcanic and features the original stages themed after Crocodile Cauldron, while the left half has a swamp terrain, including the partially submerged ship from Krem Quay. The world boss, Kleever, is found at the end. The only Krem Quay level to not return is Bramble Blast, which was relocated to Krazy Kremland in Donkey Kong Land 2.
