Poisonous Pipeline

Poisonous Pipeline is the thirty-fifth level in the Donkey Kong franchise game, Donkey Kong Country 3: Dixie Kong's Double Trouble! It is also the fifth area of KAOS Kore. In the game's Game Boy Advance remake, it is the forty-first level instead.

This level takes place in a mostly-flooded pipeline. The pipeline is filled with a poisonous, purple liquid, that can reverse the player's left and right movements. The Kongs will have to swim around with these reversed directions, which can be fairly confusing, as sometimes, they may forget about the revered directions, and move into a nearby enemy. Of these enemies include the underwater foes, Lurchins and Kocos, as well as a single Krimp found in a dry area of the stage. Though these enemies could become a problem for the heroes, they will eventually meet, Enguarde the Swordfish, who will help them defeat these foes for a short time.

Level Layout
At the beginning of the level, the heroes will swim through a long pipeline. Moving along the poisoned path with their messed up directions, they will pass many Lurchins and Kocos, who will try to hinder their progress. At the end of the long pathway, the Kongs will head through a smaller area downwards and swim to the west. They will meet more enemies here, especially the shell-covered Lurchins. Soon, they will take a small pathway down to a lower part of the level. There, they will travel east and head down the first opening they see. Continuing downwards, they will find the letter O and move to the right to find an upward pathway. Maneuvering around a few Lurchins, they will make it to a slightly higher area, where they will pass a large group of Lurchins and move downwards. They will head through a thin pipe, where they will find the Star Barrel.

About halfway through the level, the monkeys will enter another long area, where they will swim down a large pipeline and avoid countless schools of enemies. Soon, they will find two Lurchins moving through a small pathway. Going under the foes, they will make their way into another area. There, they will pass several Kocos and also find the letter K in an above alcove. Farther on, the Kongs will pass many more Lurchins, assisted by the small Kocos. Once they begin to take an upward pathway at the end of the area, they will dodge some Kocos and travel west. Shortly after going this direction, they will come up to another pathway, which they should head up. They will move around a few Lurchins as they make their way into the next part of the level, where they will travel east past more enemies. Heading up again, they will sneak between two Lurchins to see yet another upwards pathway. If they continue north from this area, they will eventually reach the surface of the poisonous gas. On the nearby platform, they will also see a flagpole. If they pull on the end of the flagpole, the level will end.

Bonus Levels

 * 1) About a fourth of the way through the level, the heroes will notice a Koco swimming between two Lurchins. They should dodge this foe and get between the Lurchins to find a Bonus Barrel. The barrel will take them to a Bonus Level, where they will need to swim through another poisoned area with Enguarde. With this fish, the player will have to defeat several enemies. Once all these enemies are beat, they will earn a Bonus Coin.
 * 2) Near the end of the level, the heroes will swim between two Lurchins around two Kocos. If they continue to the left from here, passing several Lurchins, they will find a passageway going downwards. Following this pathway, they will soon come up to a Bonus Barrel that will take them to a Bonus Level. There, they will have to swim in a large circle through the pipeline, collecting stars. If they collect all the stars withing the time limit, they will find a Bonus Coin back at the start.

DK Coin

 * 1) After the heroes find the letter G, they should jump to the surface of the liquid and land on a platform with a Koin, who will have the DK Coin. They will have to defeat him to get it. The enemy's shield will protect him from most attacks, so the heroes will have no choice but to use the nearby steel barrel. With the barrel, they should stand on the foe's shield and throw it against the wall to the right. The barrel will bounce off of the wall and hit the side of the Koin, defeating him. With the Koin knocked out, the DK Coin will be given to the Kongs.

Trivia

 * In Donkey Kong Country 2, Kaptain K. Rool shot purple clouds that had a similar effect on the Kongs.
