Kongo Jungle

The Kongo Jungle is a vast jungle covering a large area of Donkey Kong Island, located at the foot of the Monkey Mountains. It is generally depicted as the place where the Kongs reside.

Donkey Kong series
It is the first area in Donkey Kong Country, and is where Donkey Kong's house is located, as well as his precious Banana Hoard, which is often stolen by the Kremlings. The area is quite pleasant, possessing a vast amount of jungle and some rocky terrain. A large lake is also located in the area. The boss of Kongo Jungle is a giant Gnawty aptly named Very Gnawty.

The area where Donkey Kong's Treehouse is located in Donkey Kong 64 could possibly be either Kongo Jungle or a portion of it. Also, the area Jungle Japes in Donkey Kong 64 bears an extreme resemblance to Kongo Jungle.

Super Smash Bros.
Kongo Jungle (incorrectly spelled Congo Jungle) appears as one of the arenas in the game Super Smash Bros. The Kongo Jungle stage is made out of a large wooden platform with several smaller, sometimes floating ones around it. There is also a vast jungle in the background of the arena and a Barrel Cannon underneath the arena.

Super Smash Bros. Melee
In Super Smash Bros. sequel Super Smash Bros. Melee another Kongo Jungle stage was introduced. This Kongo Jungle stage is constructed out of logs strewn together which are sitting on rocks jutting out of a waterfall. In the background of this stage is a vast jungle along with what appears to be Donkey Kong's Treehouse. Occasionally, a Klap Trap will come along on the waterfall, and sometimes a log, which can be used as a platform. Also in Super Smash Bros. Melee is the old version of Kongo Jungle from the previous Super Smash Bros. game. The old version of Kongo Jungle can be unlocked by surviving Fifteen-Minute Melee. The music here was the DK Rap from Donkey Kong 64.

In Adventure Mode, Kongo Jungle stars in Stage 2: Kongo Jungle. In it, the player has to battle two miniature Donkey Kongs. They are easier to knock off the stage, but they gang up on the player. Once beating, the player moves onto the second Half, Jungle Japes, where the player must battle a Giant Donkey Kong.

Super Smash Bros. Brawl
The Melee Kongo Jungle appears in Super Smash Bros. Brawl as a returning stage with several music selections.

Trivia

 * The name Kongo Jungle is a play on words on the Congo Jungle in Africa, using a "K" instead of a "C" to imply that it is the home of the Kongs.
