Oil Drum Alley

Oil Drum Alley is the twenty-third level of Donkey Kong Country and the first level of the Kremkroc Industries, Inc.

Summary
Oil Drum Alley is the first factory level, and oil drums are the main obstacle of the level as the name suggests. Oil drums are found both on ground and over abysses, and sometimes Donkey Kong and Diddy Kong can only get across abysses by jumping from oil drums while their flames are out. There are some TNT Drums in the level, and the Kongs can use them to destroy a TNT Drum. Enemies in the level include bouncing Kritters, Gnawties, and Manky Kongs. Just after the Continue Barrel, the Kongs can open an Rambi Crate to ride Rambi the Rhino for the rest of the level.

Layout
At the beginning of the level, the Kongs can find a Gnawty walking on a cylindrical platform with a rope hanging next to it. After passing a TNT Drum in a gap, they can find a pair of Kritters hopping up some stairs. The first DK Barrel here wobbles at the edge of a ledge nearby. An oil drum with a hot flame on it stands in front of the ledge. Two Kritters hop in an area below it, moving away from a small gap with the letter K above it. An oil drum sits on a raised platform ahead that the Kongs can only get onto if they use a bouncy tire. The primates can find some stair-like structures ahead with a trio of Gnawties on them. A ledge is at the end of this area. If the duo drops down it, they can find a tire that can be used to jump over an oil drum at a higher elevation.

Another tire follows this drum with a second oil drum after it. Once they hop over this, they come up a small stairway with bananas along it. Stair-like structures lead farther down the area area ahead. Gnawties are on some of the stairs, and an oil drum is on every other ledge. A DK Barrel is located in the ground after the last stair platform. The two friends can find a small gap nearby with a Kritter hopping next to it on some smaller stairs. It is followed by a Blast Barrel that shoots the heroes onto a high area. Here, the primates can find sets of small stairs leading towards a flat pathway with a few oil drums on it. Kritters jump up the stairs. The duo soon comes up to the flat pathway, supporting four separate oil drums with flames shooting out of them. The letter O hovers above the last drum, and Kritters attack the primates as they cross the area. The level's Continue Barrel is ahead on a raised platform.

If the heroes continue, they can find an oil drum on a cylindrical platform. It is followed by a gap that has an Animal Crate with Rambi, and another area with a cylindrical platform and a Manky Kong. After passing a gap next to the ape enemy, the heroes run up a flight of stairs with a pair of Kritters near the top of them. If they drop off of the ledge at the top of the stairs, they can find a Manky Kong standing on a raised platform shaped like a cylinder. Two Kritters approach this platform, trying to attack the Kongs. Farther ahead, Donkey and Diddy can find an oil drum floating above an alcove. They can use the drum to reach a higher ledge with two more Manky Kongs on it. Both of the foes stand on dark, cylindrical platforms. A pit is ahead with an oil drum in the center of it. The drum is required to cross the gap, but it can only be jumped on when its flame is out.

The Kongs can find a Kritter and another pit on the other side of this abyss. As before, an oil drum must be used to cross it and reach a tall platform with a DK Barrel on it. An abyss much wider than the previous is located nearby with two oil drums in it. When the flames on the oil drums fade, they must use them to cross. Two Kritters attack the primates upon accessing the opposite end of the pit. A gap that must be crossed with an oil drum follows. Once it is crossed, the Kongs can find a stairway leading up to a Manky Kong, who hurls an unlimited supply of barrels at them. After dropping down a small ledge placed after the enemy, the heroes find a large abyss and a sign that indicates that the level is near complete. Several oil drums fill the gap, and the Kong must watch the pattern that the flames go out on with them; the flames only slightly diminish most of the time, but then they disappear long enough for the Kongs to cross safely. A few tires are also scattered in the pit to help the heroes pass the abyss as well. Once the two friends cross the pit, they can find a pathway leading to the exit.

Theme
The level's theme, "Fear Factory," is reused in Blackout Basement. It also makes appearances in later Donkey Kong Country games.
