Kongo Jungle (Super Smash Bros.)コンゴジャングル(Kongo Jungle) is a stage in Super Smash Bros. (incorrectly spelled Congo Jungle), in Super Smash Bros. Melee and in Super Smash Bros. for Wii U. The stage is known as Past Stage: Kongo Jungle N64 in Super Smash Bros. Melee, Kongo Jungle 64 in Super Smash Bros. for Wii U, and Kongo Jungle in Super Smash Bros. Ultimate. It is one of Donkey Kong's home stages. The stage is based on various levels from Donkey Kong Country, with pre-rendered backgrounds, environmental themes and songs, and most notable in a battle, use of the Barrel Cannon for transportation (usually for a vertical recovery).
This lush arena is a fertile spot for a friendly fight. A large wooden deck serves as the base for battle, with two perilous platforms rotating counterclockwise overhead. A barrel cannon constantly moves back and forth beneath the arena, which can give unlucky players one last chance to avoid falling to their demise.
This stage appears as a starter stage in Super Smash Bros. This stage is made up of a big platform with four small platforms above it. Two small stationary platforms are above the left and right sections of the stage, and between them are two smaller platforms that circulate clockwise. The main platform can be passed through from below, but not from above. Under the stage there is a Barrel Cannon that can greatly aid many characters' recovery. A player that gets into the barrel can exit either by pressing a button or waiting for a certain period of time. In either case, they will be shot in the direction that the arrow on the barrel is currently pointing. There can only be one character at the time in the barrel.
This stage is a legal stage.
In Super Smash Bros. Melee, this stage is one of the three past stages that can be unlocked. To unlock, the player must beat 15-Minute Melee. The stage itself is a near-exact copy of the SSB version, only being slightly larger. There also seems to be a short delay when the player is launched from the barrel, which can almost always spell doom for the mis-aimed character in many cases.
The stage once again returns in Super Smash Bros. for Wii U, and like in Melee, is an unlockable stage. To unlock, the player must clear the event "The Original Heavyweights". Like other returning stages from the first Smash game, some of the textures are slightly higher in quality, but the general overall primitive look of the original is retained.
The stage returns yet again in Super Smash Bros. Ultimate, but this time is a starter stage since Super Smash Bros. 64.
This stage comes from Donkey Kong Country. In 'the level called Blackout Basement, there are two platforms that oscillate up and down. Later in the game is a level called Platform Perils which has platforms with arrows on them that move when the player jumps on them and they move in the direction that the arrow is pointing. These levels may bring the elements of the moving platforms of this stage.
Also from Donkey Kong Country are barrels that the player could get shot out of. Certain barrels can move up and down, left and right, or move diagonally. There were also barrels that remained stationary, but they rotated around. In Donkey Kong Country 2 there are arrow barrels that fire at whatever direction it is pointing. In this stage there is an arrow barrel, but the barrel also moves side to side and can rotate. In the background near the sunset, a flock of Neckies can sometimes be seen flying across the horizon. In Donkey Kong Country, Neckies were among the most common enemies 
The song that plays on this stage is from Donkey Kong Country's Jungle levels. 
- This is the first Past stage in the Super Smash Bros. series to not appear in one game (Brawl) then return in its successor (Super Smash Bros. for Wii U).
- This is the first past stage from the original game to return in Super Smash Bros. for Nintendo 3DS / Wii U.
- This stage has had a different name in every appearance. In Super Smash Bros., it is called "Congo Jungle"; in Melee, it is called "Past Stages: Kongo Jungle N64" on the stage select screen and "Kongo Jungle N64" in the Random Stage switch; and in Smash for Wii U, it is called "Kongo Jungle 64" in NTSC versions and "Kongo Jungle (64)" in PAL versions.
- Oddly in Smash for Wii U, this stage's Spanish name makes no mention of its appearance in the Nintendo 64 game, being named Jungla Kong (Kong Jungle) in PAL versions and Selva Kongo (Kongo Jungle) in NTSC versions without any "64" suffix.
- The misspelling "Congo" in this stage's first outing might be due to the fact that two countries in Africa, as well as a river that runs through them, are spelled "Congo". The location in Donkey Kong Country which this stage's name is attributed to is actually called "Kongo Jungle".
- This is the only Smash 64 stage exclusive to Smash Wii U, as it is also the only Smash 64 stage that isn't downloadable content.
- It is also the only Smash 64 stage in Smash for Wii U / 3DS that doesn't have "64" in parentheses.
