Oil Drum

Oil Drums are oil drums that either produce fire or Donkey Kong Country or Donkey Kong Land enemies.

Donkey Kong
The Oil Drum makes it's first appearance in the arcade game Donkey Kong, in which Donkey Kong drops an Oil Drum on the barrel that is right behind Mario when he starts the level, producing a Hot Foot, which appears again in Super Mario Bros 3.

Donkey Kong Country
Oil Drums appear again in Donkey Kong Country but this time not only do they produce fire but they also produce enemies. An Oil Drum is also a boss in Donkey Kong Country, under the title Dumb Drum, in which a big Oil Drum tries to fall on the Kongs resulting in killing one of them if he suceeds or spits out enemies. After several rounds of ememies the drum attempts to smash the Kongs one last time but blows himself up in doing so.

Donkey Kong Land
The Oil Drums appear again in Donkey Kong Land but have the same abilities as in Donkey Kong Country.

Donkey Kong Country 2
In Klubba's Koisk there is a tipped over Oil Drum in the background.

Donkey Kong Land 2
Same as Donkey Kong Country 2.

Mario vs. Donkey Kong 2: March of the Minis
In Mario vs. Donkey Kong 2: March of the Minis the Oil Drums work the same way as they do in the arcade title: Donkey Kong. They appear in every level except the final boss.

DK: Jungle Climber
They also appear in DK: Jungle Climber but under the name Oil Barrel and are now collectible items.
