Lost World (Donkey Kong Country 2: Diddy's Kong Quest)

The Lost World is a secret area and world of Crocodile Isle in Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. In both games, the area is guarded by Klubba at his tollbooth, Klubba's Kiosk, as he was ordered by Kaptain K. Rool to do so.

The Lost World is the power source of Crocodile Isle. The energy is generated from Krocodile Kore, a temple shaped like a Kremling head integrated into a volcano in the world's central lake. Krocodile Kore also acts like a geothermal vent from sending out an upward stream of purple, white and blue energy. The Lost World has a variety of climates, including jungles, frozen caverns, and volcanic. There are tall, gray, and white-capped rocky hills that encircle the upper part of the location. In the Game Boy Advance version, like the other worlds, the overworld view of the Lost World was redesigned, and shows a wider, zoomed in display of its hosted environments.

History
In Donkey Kong Country 2: Diddy's Kong Quest, there is a Klubba's Kiosk in most worlds, starting with Crocodile Cauldron and ending with K. Rool's Keep. In each world, Diddy Kong and Dixie Kong can pay 15 Kremkoins to Klubba to access a level of the Lost World. There are five levels in the Lost World, and the Kongs must pay 75 Kremkoins in total to access the entire Lost World.

In Donkey Kong Land 2, there is only one Klubba's Kiosk, which appears on the Crocodile Isle map, left of Gloomy Gulch. Unlike the previous game, the Kongs cannot pay Klubba per each individual level, and must make a one-time payment of 47 Kremkoins to access the entire Lost World. The overworld has a similar appearance but still features some differences including: a larger lake, the Krocodile Kore's mouth always being open, and a geyser of energy no longer emitting from Krocodile Kore.

In the ending for both games, K. Rool gets launched into the energy flow of Krocodile Kore. He blocks the flow of energy, causing it to build up and eventually explode Krocodile Kore. Diddy and Dixie escape from the Lost World before it and Crocodile Isle sink underwater.

Levels
In both games, after the Kongs complete all five levels, the mouth of Krocodile Kore opens, allowing them to enter inside.
 * Jungle Jinx (jungle)
 * Black Ice Battle (ice cavern)
 * Klobber Karnage (jungle)
 * Fiery Furnace (volcano)
 * Animal Antics (jungle, ice cavern, bramble)
 * Boss level: Krocodile Kore (lair)

Appearances in other media
The German Donkey Kong comic Bumm-Badabumm im Urwald featured a place called the "Lost Land". Despite being located on Donkey Kong Island, the Lost Land was seemingly the Bumm-Badabumm im Urwald version of the Lost World, as it is filled with ancient Kremling ruins and it is where the Kongs have their battle against Kaptain K. Rool.

Trivia

 * The name may be a reference to the of the same name, its, or the , released a few months prior to Donkey Kong Country 2. However, the idea of an underground jungle seems to be borrowed from  by Jules Verne.
