Dumb Drum is the third-from-last boss in Donkey Kong Country. He will slam down a few times (the first time once, the second time twice, and so on) then he will pour out a few enemies. First, two Kritters come out of the Dumb Drum, then it's two Slippas, then two Klaptraps, next two Klumps, and finally two Armys. The last time he slams down he explodes, and the giant banana is yours.
