Crocodile Cauldron

Crocodile Cauldron is the volcanic mountain range of Crocodile Isle and the second world of Donkey Kong Country 2: Diddy's Kong Quest. It has Kleever as the world boss. In Donkey Kong Land 2, Crocodile Cauldron does not appear as a standalone world and was combined with Krem Quay to form the world Krem Cauldron.

Crocodile Cauldron has several rivers of lava, large pitfalls, and a prominent at the top. The world appears to be encased in a cave carved in the shape of a giant Kremling skull, which has glowing, red eyes, and steam coming out from the nostrils. Aside from volcanic areas, Crocodile Cauldron features a few mine shafts, from which the Kremling Krew would excavate gems and minerals. There is also a large, broken galleon which is partially submerged in the lava. Water also seems to flow through Crocodile Cauldron, or there is at least a large deposit of it underground, as the ship remains are flooded with it. Three levels take place at a volcanic area (one of which is the boss battle), two levels take place in mine shafts, and one level takes place in the broken galleon. The Game Boy Advance version of the map, notably, has more solid ground that can be traversed.

In the ending, Crocodile Cauldron and the rest of Crocodile Isle sinks into the ocean.

According to the Player's Guide, the lava pools from Crocodile Cauldron are the Kremlings' source of heat and power in Crocodile Isle.

 * Instruction booklet : "Visitors venturing onto Crocodile Isle receive a warm reception from the bubbling lava of Crocodile Cauldron. The key to these levels is to avoid getting burned in the ever-present red-hot lava. Fortunately, there are many different ways to keep your feet cool: crocodile heads provide safe stepping stones in one area, and hot-air balloons will give you a ride in another."
 * Player's Guide : "Talk about out of the frying pan and into the fire! The lava pools and gas jets of this volcano are source of heat and power for the Kremlings and an endless source of frustation for you!"
 * Nintendo Power : "Leave it to the good Kaptain to plant his headquarters on a dangerous volcanic island! Besides the scores of enemies, you'll have to deal with seething lava pits and boiling underground lakes. Though the stages aren't timed, many of the situations demand that you make a move within a few moments or disaster will strike. At other times, there may be several bonus items in front of you, but no way to collect all of them safely. There may be no single correct move, but what you do may mean the difference between being able to afford advice, playing Klubba's toll or gaining some extra lives. The choice is yours, matey!"
