Orang-utan Gang

Orang-utan Gang is the fifteenth level of Donkey Kong Country and the fifth level of Vine Valley. In the Game Boy Advance remake, Orang-utan Gang was shifted to the fourth level of Vine Valley, making it the fourteenth level overall. By completing the level, the Kongs can access Cranky's Cabin and the next level, Clam City.

Summary
Orang-utan Gang is the last jungle level in the game, and it involves Donkey Kong and Diddy Kong having to walk along the treetops. It is the first level with Manky Kongs, who stand on the treetops and throw barrels at Donkey Kong and Diddy Kong. Shortly before the Star Barrel, the Kongs can jump on an Animal Crate to release Expresso the Ostrich and ride him for the rest of the level. There are five Bonus Levels in Orang-utan Gang, the most of any level in the Donkey Kong series, and Expresso is required to reach a Bonus Level hidden under the start of the level.

At the start of the level, if Donkey Kong and Diddy walk left, they can pick up a Steel Barrel on a tree, circled by a Zinger. If they pick it up and throw it to the treetop on the left, the Kongs can jump on the rolling Steel Barrel to ride through most of the beginning portion of the level.

In the original version, the level starts during the day and gradually transitions to sunset. In the Game Boy Color version, the entire level takes place during the daytime. In the Game Boy Advance version, the entire level takes place during a sunset.

Layout
The Kongs begin the level on a long line of treetops that are followed by two higher treetops. The sets of trees are connected by vines that Kritters bounce along. Behind this area, the primates can find a Zinger circling a Steel Barrel. Another vine is ahead of the area that connects the previously mentioned pair of trees to another pair. A curved trail of bananas nearby lead the heroes onto a solid area of land with a Klaptrap on it. The Kongs can find more land below it that holds a DK Barrel and another Klaptrap. This area of ground is followed by a large abyss containing three sets of treetops that are all connected by two strong vines that can hold the Kongs' weight. They also hold up the many Kritters that hop along them. A small gap is present after the third set of trees, and a Zinger circles the letter K above it. Four more sets of treetops are ahead, all of them having vines to be used as bridges. After reaching the fourth set of treetops in this area, the Kongs can find a large piece of land ahead of them the consists of many ledges that hold a few Klaptraps. The bottom of the land area features a few small gaps. A small platform between the pits holds the letter O. The duo can also find a crate containing Expresso on the top of the area, which is followed by a set of treetops that hold the level's Star Barrel and a Klaptrap.

A small gap separates these trees from the following treetop, but the primates can cross it with a simple jump. The primates can find the second DK Barrel in the level on the top of the lone tree following the abyss. The tree is connected by a vine to a group of four neighboring treetops that hold a barrel-throwing Manky Kong. The vine can be used as a bridge to reach the trees, which are followed by a small pit with another tree standing in it. They can find a Steel Barrel on top of the large plant. After crossing another small pit, the primates reach a lone tree that is connected to another two trees by a vine that the heroes can travel along. The two trees at the end of the vine carry a Manky Kong. A small pit is ahead of the foe that is followed by two more trees that are connected to another pair of trees with a vine. Barrels from a nearby Manky Kong roll down the vine as the Kongs travel along it. After they pass this Manky Kong, they make their way onto another area of land that consists of a few large ledges. A path hangs off of the front of the area that the Kongs can walk along to find a Klaptrap and the letter N. They can find an additional Klaptrap on a higher part of the large platform, which is immediately followed by a pair of trees that hold a DK Barrel.

Four more sets of trees stand in the abyss ahead of here. They are all connected by slanted vines that hold several Kritters. Two Manky Kongs are also located in the middle and end of the area, hurling barrels down the vine bridges. Once they pass the second Manky Kong, they reach another large area of land that features a large alcove containing two Kritters. A barrel also sits on the end of it. The Kongs can also find a tall piece of land behind it that they can reach with Expresso. A tire that can help the Kongs break some distinguished pieces of the ground on this raised area. Objects, such as a DK Barrel, are released from the ground when they are broken. After the heroes make their way across the whole area of land, they find two pairs of trees that are connected by twisted vines that they can use as bridges. A Manky Kong hurls barrels down the vine as they progress. Once the heroes pass the Manky Kong, they reach a large area of land with a sign on it, indicating that the level is near complete. If they manage to climb over a raised piece of land with a Kritter on it, they find an exit sign. A tunnel leading out of the level is ahead of it.
