From the Super Mario Wiki
Krem Cauldron is the name of the second area of Donkey Kong Land 2. It is a combination of Krem Quay and Crocodile Cauldron from Donkey Kong Country 2: Diddy's Kong Quest. The area features 10 levels, five from Crocodile Cauldron and five from Krem Quay. With 10 levels and a boss area, it's the world with the most levels in Donkey Kong Land 2.
The right half of Krem Cauldron is full of volcanoes where the five original levels from Crocodile Cauldron can be found. The left half of Krem Cauldron features a half submerged ship that was originally in Krem Quay and the other five levels as well as the boss are located there. "Bramble Blast," which was originally in Krem Quay in Donkey Kong Country 2, is now located in Krazy Kremland.
Once the Kongs manage to beat all 10 levels of Krem Cauldron, they have to fight Kleaver.
