Dumb Drum is the fifth boss in Donkey Kong Country resembling a giant Oil Drum. Dumb Drum appears in the world Kremkroc Industries Inc. It appears to have a skull and two crossbones along with red eyes put on it. Like regular Oil Drums, Dumb Drum spits out enemies.
Dumb Drum attempts to smash down on the Kongs a couple of times, then sends out enemies. The first enemy Dumb Drum sends out are Kritters. After that, the Kongs must continue avoiding Dumb Drum and defeat the Klaptraps, Armies, Klumps, and Slippas. If the Kongs manage to defeat all of the enemies, Dumb Drum collapses and the Kongs can move on to Chimp Caverns.
