Oil drum

Oil Drums, also known as Oil Cans , are cylindrical metal drums filled with oil that have the ability to produce Fire creatures or other monsters from themselves. They are indefatigable obstacles that recur throughout the Donkey Kong franchise.

Donkey Kong
An Oil Drum is first featured as a hazard in the 25m stage of the Donkey Kong arcade game. It appears on the bottom floor, left from Jumpman's starting position. Although harmless itself, the Oil Drum will combust into flames when a blue barrel is tossed into it, producing Fire enemies which seek and attempt to harm Jumpman.

The Oil Drum is seen again and acts the same in the Game Boy Donkey Kong rendition of 25m, as well as in Donkey Kong 64's port of the original arcade game.

Donkey Kong Country
Oil Drums later appear as obstacles in Donkey Kong Country. They retain their ability to expel flames. They are the main feature of the first Kremkroc Industries Inc. stage, Oil Drum Alley, but they also appear in Torchlight Trouble. Some Oil Barrels continuously expel flames, while others do so every few seconds. They are either positioned on the ground or in mid-air. In parts of Oil Drum Alley, Donkey and Diddy are required to cross abysses by hopping from one floating Oil Drum to the next. The only way to destroy an Oil Drum is by throwing a TNT Barrel at it. This is necessary at the beginning of Oil Drum Alley in order to access the level's first Bonus Level.

Black Drums are similar enemy obstacles to Oil Drums. Appearance-wise, they are more slim and have a skull and crossbones emblem printed on them. These obstacles emit an unlimited amount of a certain enemy. Dumb Drum is a larger boss variant of an Oil Drum, but its attack pattern is based on that of a Black Drum's.

Donkey Kong Land
Oil Drums appear again in Donkey Kong Land, where they are preponderant in the level Oil Drum Slum. They act the same as in Donkey Kong Country.

Donkey Kong Country 2: Diddy's Kong Quest / Donkey Kong Land 2
A tipped over Oil Drum appears in the background of Klubba's Kiosk in both Donkey Kong Country 2 and Donkey Kong Land 2. It has no effect on gameplay.

DK: Jungle Climber
While Oil Drums do not appear in DK: Jungle Climber, it features similar objects, known as Oil Barrels, that are used to fuel Funky Kong's Barrel Plane.

Mario vs. Donkey Kong
Traditional Oil Drums are not in Mario vs. Donkey Kong; however, the Oil enemy from the Game Boy Donkey Kong reappears, redesigned with a drum covering its lower half.

Mario vs. Donkey Kong 2: March of the Minis
In Mario vs. Donkey Kong 2: March of the Minis, Oil Drums work the same as in the original Donkey Kong, where if Donkey Kong throws a barrel and it lands in an Oil Drum it will create a Fire enemy. They only appear in the final battle against Donkey Kong.

WarioWare series
An Oil Drum makes a minor appearance in the Donkey Kong microgame from both WarioWare: D.I.Y. Showcase and WarioWare Gold. It stands in the bottom left corner of the screen just like in the 25m stage from the original arcade game, this time with no bearing on gameplay.

Mario Party 10
A small burning oil drum looking similar to the one from the arcade Donkey Kong makes an appearance on the Donkey Kong Board from Mario Party 10. It can be seen next to a Special Dice Block Space on the right side of the board. Additionally, 8-bit sprite renders of Oil Drums are engraved on two blocks in the north-western part of the board.

Super Mario Odyssey
In Super Mario Odyssey, Oil Drums are found in 8-bit segments in the Metro Kingdom and the Darker Side, using their appearance from Donkey Kong. Touching an Oil Drum causes Mario to take damage.

Mario + Rabbids Kingdom Battle
One of Rabbid Cranky's Barrel Bolts in the Donkey Kong Adventure DLC of Mario + Rabbids Kingdom Battle is styled after an Oil Drum from its original arcade appearance. Its description even states that foes will not turn into flames with eyes when hit by this, a reference to the Fire enemies.
