The Volcano is the eighth world of Donkey Kong Country Returns and Donkey Kong Country Returns 3D. It can be accessed after defeating Colonel Pluck and his Stompybot 3000. It is located on Donkey Kong Island, and is a very dangerous area. During the events of the game, it is infested by members of the Tiki Tak Tribe, who have stolen Donkey Kong's and Diddy Kong's banana hoard. This world is also home to the Tiki Tak Tribe's leader and the game's final boss, Tiki Tong.
The Volcano is a very dangerous world, and as its name implies, it takes place in a volcanic area. It features many new elements not seen in the game's previous worlds, such as lava that will instantly take out the Kongs and fireballs that move in a set pattern. There are structures that sink into the lava when stepped on and platforms that appear for a set period, then sink back into the lava. This area also brings back many elements from the past worlds, such as turf, minecarts, Rocket Barrels, vines, and even Rambi. The levels in this world are all diverse and use different mechanics.
