Black drum

Black Drums are steel drum obstacles that appear in a few levels of Donkey Kong Country. Each Black Drum has the ability to spawn an unlimited number of a specific enemy, either Gnawties, Armies, Klaptraps, or Slippas. An enemy comes out of a Black Drum every few seconds. Black Drums first appear in Winky's Walkway and last appear in the Chimp Caverns level, Misty Mine, as the stage's main obstacle.

The fifth boss, Dumb Drum, is a larger variant of a Black Drum. It has the ability to spawn larger enemies that normal ones cannot, including Kritters and Klumps. Black Drums also have a similar variant, Oil Drums, that emit flames instead of enemies.
