Poisonous Pipeline is a level in Donkey Kong Country 3: Dixie Kong's Double Trouble, and the fifth area of KAOS Kore.
In this mostly-flooded pipeline, there is a purple liquid that will reverse the player's controls, reversing right and left movements. The Kongs will have to swim around with these reversed directions, which can be fairly confusing. However, with some caution this level won't seem to difficult. Enguarde can also be found here, and is playable for part of the level. Lurchins, Kocos and a single Krimp are enemies here.
