Orang-utan Gang

Orang-utan Gang is the fifteenth level of the classic Super Nintendo game, Donkey Kong Country, as well as the fourteenth level in its Game Boy Advance remake. It is also the fifth level of the Vine Valley area in the original Donkey Kong Country, along with the fourth area of the same world in the Game Boy Advance version (due to Temple Tempest being pushed to the sixth level of the world).

This level takes place in the treetops of a jungle. Throughout the level, Donkey and Diddy Kong have to run tree-to-tree on lush, green vines and treetops in this dark jungle. Their journey through the jungles leads them to the Kong reject orangutans: Manky Kongs. These dark orange-colored apes hurl dozens of barrels at the heroes without breaking a sweat, and they can be quite a hazard. Along with these dangerous foes are the members of the Kremling Krew, Klaptraps, Kritters, and Zingers. Although the level is crawling with vicious enemies, the Kongs can get backup in the form of an Animal Buddy, known as Expresso the Ostrich. This buddy can flutter through the air for a short period of time and help the heroes avoid obstacles, or even get them into Bonus Levels.

Level Layout
From the start of the level, the heroes must walk along the vines and treetops over the bright green jungle and defeat a few Kritters. Soon, they will find themselves on a large platform with two Klaptraps. They should beat the enemies and run across the treetops to the right. On the way, they will encounter several foes, including a Zinger, guarding the letter K. Eventually, the Kongs will walk down a few vines to find land again. They should journey farther eastward here and jump up the many ledge of the area to find a crate. Expresso is in the crate, and they can ride on him throughout the rest of the level. After that, the group must head to the right and get back on the treetops, where the Star Barrel is found.

Halfway through the level, the monkeys and their animal friend must travel east and encounter a Manky Kong. The villainous monkey should be defeated, and then the heroes must continue along the treetops, beating a few more Manky Kongs. Farther on, Donkey, Diddy and Expresso will find themselves on solid ground again, where they can find the letter N, as well as a few foes to defeat. Carrying on, the group will get back on the treetops and have to head a long distance across some twisted vines. Manky Kongs and Klaptraps will try to hinder their progress as they make it through the area, so the heroes must be careful. When they get back to land again, the Kongs and Expresso will need to beat a few Kritters hidden in a small alcove and pass a barrel to get back on the treetops. There, they must trudge up a vine and dodge a lone Manky Kong. Soon, they will make it to solid ground, where they must jump up a ledge to find an exit sign. Farther on is a cave leading to the next level.

K-O-N-G Letters

 * K: Near the beginning of the level, the Kongs can find a small gap between the treetops with a Zinger circling the letter K above it.
 * O: The letter O is directly under Expresso's Animal Crate on a small platform. The primates must make a small jump in order to cross the small abyss next to it, for if they jump too high, they land on the higher piece of land instead.
 * N: An area full of Klaptraps is loacted immediately before the second DK Barrel from the Star Barrel. The letter N stands on the edge of a low cliff at the bottom of this area.
 * G: The primates should slam onto a distinguished piece of ground in the fourth Bonus Level to break the letter G from underground.

Bonus Levels

 * To find the first Bonus Level, the Kongs must travel about halfway through the level and find Expresso. When they get on the ostrich buddy, they should head west and travel backwards. When the group makes it to the area in the beginning of the level where two Klaptraps were once found, they have to jump off the edge of the cliff to the left. In the air, Expresso should flutter under the treetops as far as he can go. Soon, the heroes reach a hidden platform with a small cave. They must walk into the entrance to enter the first Bonus Level, where they need to hit several moving letters, which orbit the area. They must be hit in the correct order to spell out an Animal Buddy's name, particularly "Winky." If they touch all of the letters in the correct order, they are awarded with an Animal Token of the animal name they have spelled out, and then exit the bonus.
 * To get in the second Bonus Level, the heroes must make sure they have Expresso with them, and then travel to the area with the letter N. Expresso, with the Kongs on him, should jump off of the cliff and flutter over an abyss to the right until he lands on a safe platform. There, they must fly over another abyss and land in an area with a barrel. The Kongs must dismount from the ostrich and break open a nearby wall to reveal an opening. If they walk into it, they are sent into a Bonus Level, where they have to bounce off of a tire and land on certain parts of the ground to find special items, including a DK Barrel, an Extra Life Balloon, and a Banana Bunch. They can exit the stage when they are done through a small opening.
 * Shortly after exiting the second Bonus Level, the Kongs discover a lone barrel near the treetops. They should pick it up and jump into the small abyss to the right to land in a hidden area. There, they need to fall through the next small gap, still holding the barrel, and then blast open the wall to the left. When it breaks, they must walk into the opening and get into the Bonus Level. There, they must bounce off of a tire and land on two distinguished areas of the ground to win two Extra Life Balloons. Once done, they can exit through a nearby opening.
 * When the heroes get out of the third Bonus Level, they end up next to a barrel. Just as before, they must jump through the closest abyss and land in a hidden area. At this point, they must jump over a small gap, where the third Bonus Level was found before and bust open the wall to the right. An entryway appears as a result, and they should walk into it to enter the fourth Bonus Level. In this special level, the need to bounce off of a lone tire and land on a distinguished area on the ground to find the letter G. Once they are finished with this, they can exit the stage through a small opening.
 * When the Kongs discover the level's final Manky Kong, they should jump to the right of him and wait a moment. Once the foe throws a barrel at them, they need to hop over it and watch as the barrel crashes into a nearby wall, located near a sign that indicates that the end of the level is nearby. It creates an opening in the wall, which the Kongs must walk into to enter the stage's fifth Bonus Level. There, they have to break a crate with Expresso in it. When the bird is found, they should get on him and ride over a wide abyss, collecting many bananas on the way. At the end of the stage, they can find an Extra Life Balloon to collect, as well as the way out of the stage.

Photograph (Game Boy Advance version only)

 * Expresso and the Kongs fly into a camera icon as they travel towards the entrance to the first Bonus Level. The item gives them a photograph of Diddy Kong riding Expresso for their scrapbook.
