Orang-utan Gang

Orang-utan Gang is the fifteenth level of Donkey Kong Country and the fourteenth level of its Game Boy Advance remake. It is the fifth level of Vine Valley 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 during sunset. The area introduces Manky Kongs, who throw barrels at the heroes. Expresso the Ostrich also appears and can help the Kongs reach Bonus Areas. This level has the most Bonus Areas in the game, with a total of five.

Overview
The Kongs begin the level on a line of treetops. The sets of trees in the level are connected by vines. Behind the start, the primates can find a Zinger circling a Steel Barrel. A curved trail of bananas nearby lead the heroes to a solid area of land with a DK Barrel and two Klaptraps on it. This area is followed by more treetops with Kritters hopping along them and a Zinger circling the K Letter in the middle. Afterwards, the Kongs find a large piece of land containing Klaptraps, the letter O, and a crate containing Expresso. This is followed by a set of treetops that hold the level's Star Barrel and a Klaptrap.

A second DK Barrel is found on another tree before three more Manky Kongs, with a Steel Barrel after the first one. Afterwards, the Kongs make their way onto another area of land with three Klaptraps and the letter N, with more Manky Kongs and Kritters. Once the heroes pass the second Manky Kong, they reach another large area of land that features a large alcove containing two Kritters, and barrel sitting on the end of it. Above it is a tall piece of land that can be reached with Expresso, containing a Tire that can help the Kongs break two ground patches that release items. Next, one last set of trees containing a Manky Kong appears. Once the heroes pass it, they reach the exit, with a Kritter in the way.

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 Kongs 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 Kongs should slam onto a distinguished piece of ground in the fourth Bonus Level to break the letter G from underground.

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.

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 left. 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 each animal friend's name, with the order being Winky, Rambi, Enguarde, and Expresso. 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 can 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 first 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 or Banana Bunches. Once done, they can exit through a nearby opening.
 * When the heroes get out of the third Bonus Level, they end up next to the same barrel. Just as before, they must jump through the closest abyss and land in the 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 bonus 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.
