The Kongo Jungle is a vast jungle in the game Donkey Kong Country, located on Donkey Kong Island and at the foot of Monkey Mines. It is the earliest residence of the Kong Family, which has since been replaced with areas like the Jungle in Donkey Kong Country Returns.
Kongo Jungle's name is based on the Congo Jungle in Africa. The only difference is that its name starts with a "K" instead of a "C"; this is a recurring theme throughout the Donkey Kong series, and Kongo Jungle is the earliest example of such.
Donkey Kong Country
Kongo Jungle is the first world in Donkey Kong Country. Most of the area is engulfed in a jungle, but features a long cavern about midway through. The cavern's exit leads to the second half of Kongo Jungle, which itself directly leads to a large lake.
Donkey Kong Country television series
Kongo Jungle reappears as the Kongs' residence for the Donkey Kong Country television series.
Super Smash Bros. series
Kongo Jungle (spelled "Congo Jungle" in the original Super Smash Bros.) appears as one of the arenas in 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. In Super Smash Bros. Melee, in addition to the previous Kongo Jungle returning, another Kongo Jungle stage (later renamed "Kongo Falls" in Super Smash Bros. Ultimate) 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 DK's Tree House. Kongo Jungle in Super Smash Bros. later returns in Super Smash Bros. for Wii U, while both versions reappear in Super Smash Bros. Ultimate.
A recreation of the original Kongo Jungle world map appears in Super Smash Bros. Ultimate's Adventure mode, World of Light, where it is named "DK Island". It can be visited via a portal on the east side of the world map. In DK Island, Donkey Kong-series spirits appear in the locations the levels were originally, in the following order: Kritter (Ropey Rampage), Cranky Kong (Cranky's Cabin), Zinger (Reptile Rumble), Enguarde (Coral Capers), Funky Kong (Funky's Flights), Candy Kong (Candy's Save Point), and Diddy Kong (Very Gnawty's Lair). Defeating Funky Kong's puppet fighter unlocks Funky Kong's Shack, one of the shops in Spirits mode.
