The Jungle (ジャングル, Jungle) is the 4th stage in the Subspace Emissary. It was first seen in the video on the Smash Bros. DOJO!! called Donkey Kong Makes His Stand. The stage itself has some special features not found on other stages. One feature is special vines that can be swung on in certain areas. Donkey Kong and Diddy Kong both come from this thickly forested area. The Jungle is populated by an assortment of Subspace enemies, such as the Hammer Bro, Koopa, Koopa Paratroopa, and Goomba.
In the cutscene, a Hammer Bro is driving a floating cart full of bananas down a path while Donkey Kong is clobbering some Koopa Troopas and Goombas. He then leaps out, roars, and looks for his stolen banana hoard. He spots his stolen bananas and a Goomba fires some Bullet Bills at Donkey Kong. Diddy Kong then leaps into the scene and uses his Peanut Popguns to blast those Bullet Bills away. After Diddy takes care of the Bullet Bills, the two apes join up and decide to go after their bananas.
The player has to choose to play as Donkey Kong or Diddy Kong. Once the player reaches the right edge they will find a Barrel Cannon. The player should ignore the next barrel cannon and head right to the next barrel cannon aiming down towards some breakable blocks. Jumping into it will blast the character through the breakable blocks down an orange cube. Next to the character, there is a switch, and hitting it will make another barrel cannon appear. After jumping into it, it will shoot the character back up to the ledge they were previously on. The player then has to head to the right. Soon, the player will find a barrel cannon going up and down though in the middle of the path. The player has to shoot themselves from barrel to barrel. The player then reaches solid ground again and will find a door.
The player has to head to the right and then has to climb some stone platforms to the top. The player has to proceed to the right. The player should hit the Trackball to find a trophy at the end. And then, the player has to go upwards and climb another ladder. Hit the Trackball and it will reveal a hidden door. Inside, the player comes out in the middle of a giant water wheel. Some Koopa Troopas and Goombas are on the ground with two green cubes on the floor, one to the left and one to the right. The player can grab these items, go back through the door and head right. Then, can hit the ball and wait for a rising stone platform to come up. Then, jump on it. Continue to the right. Hitting one of the pink balls will break the destructible wall near the right end. Here, the player will be thrown into a forced battle with Goombas, Bullet Bills, and Hammer Bros. After all the foes are beaten, the player has to head right to find a barrel cannon and finally through a door to the next section of this stage.
The player starts on a moving platform that gradually rises upwards. Enemies will keep dropping. Soon, some Bullet Bills will start going across the screen. Also, once they start appearing, a trophy will appear on the player's right on a small ledge. The player will later see a door at the top.
Jump down a cliff. There will be some Jyks in midair. The player should hold left to land on a platform with a door. Inside, there are some green cubes and an orange cube. After leaving the hidden room, continue to fall down. Eventually the player will land on the ground and some normal sized and giant sized Goombas will appear. Once the player beat all the Goombas, the golden door will appear.
At the end of the stage, there's another cutscene. In it, Donkey and Diddy Kong finally reach their banana hoard, only to find Bowser. Bowser whips out his Dark Cannon and aims for Diddy. DK punches Diddy out of the way and takes the shot, falling to the ground as a trophy. Bowser walks away with the DK trophy. Diddy Kong will join the player's team afterwards.
