Fiery Furnace (Donkey Kong Country 2: Diddy's Kong Quest)

Fiery Furnace is the fourth level of the Lost World. It can be accessed via Klubba's Kiosk in Gloomy Gulch.

This level is set in a volcano, and the Kongs must use special Steerable Barrels unique to the level in order to cross the lava. Since the Steerable Barrels are timed, and because Zingers are in the Kongs' path, it is difficult to get through this level. The barrels are scattered throughout the level, and the Kongs will have to maneuver around the area with them, without hitting enemies. Other than Zingers, the enemies here include Kutlass, Klampons, Krooks, Spinys, Flitters, and Cat-O'-9-Tails.

Level layout
At the start of the level, the Kongs must journey east and defeat some Spinies. Soon, they will come up to the first Steerable Barrel, which should be used to float over a dangerous Kutlass. After that, the heroes will have to climb up a few ledges and dodge several Klampons, until they get to the first large abyss of the level. The Steerable Barrels above it must be used to cross, although the monkeys must be careful, as there is a time limit on them. Once on the other side, they will need to watch out for a few enemies and get into another Steerable Barrel. While watching the time limit, they must maneuver around many Zingers and soon get to the other side. Here, they will have to avoid some more foes, including more Spinies. Eventually, they will bounce off of a Flitter and continue to travel through the barrels. As they shoot to each Steerable Barrel, the monkeys will need to be aided by some Flitters, so they can bounce off of them and get to another barrel. Soon, they will be shot to a group of three Flitters, and they should hop off of them to reach land, where the Star Barrel is.

Halfway through the level, the heroes will need to dodge or beat a Kutlass and a Krook. Then they must hop aboard another Steerable Barrel and journey across a wide gap. If they can dodge the many Zingers scattered around, they will make it back to land again, and shortly plop right back into another barrel. After they blast their way to the other end of the gap with the many Steerable Barrels, they will have to avoid a few more enemies, including the pesky Cat-O'-9-Tails. After passing these foes, the group must get in another barrel and steer their way to the next barrel. Although there is more time than usual on the barrel's limit, the other barrel is a longer distance away, so the monkey must move fast. When they get to land again, they must make a well-timed jump and defeat more Cat-O'-9-Tails in their path. From there, they will have to get into more Steerable Barrels and float above a dangerous abyss. This time, many Zingers are moving about to attack the Kongs, but they can be avoided with some good skills. Once on the other side, the Kongs must beat more Cat-O'-9-Tails and cross two small abysses, until they finally find the End of Level Target. It will take them out for the level when hit.

Bonus Level(s)

 * Near the end of the level, the Kongs will notice a trail of bananas above a Cat-O'-9-Tails leading up to a Steerable Barrel. They must use their Team Up move to throw a monkey into the barrel and pilot over the trail. Soon, they will reach the Bonus Barrel. In its Bonus Level, the heroes must maneuver through a bramble area inside the Steerable Barrel. The track is thin, and they may not hit the spikes on the side, as well as the Zingers. If they do hit them, they'll be taken out of the bonus. Once at the end of the stage, they must shoot out of the barrel and grab the DK Coin.

Golden Feather (Game Boy Advance version only)

 * While crossing the abyss where the letter O is found, they Kongs should come across the Golden Feather. It is between two Zingers, though, so they must use more of their skills to get it.

Photograph (Game Boy Advance version only)

 * When the Kongs reach the area under the letter G, they should see two Cat-O'-9-Tails. If they defeat the foes, they are given a photograph for their scrapbook.
