Gōrumondo act as mini-bosses by trying to prevent Donkey Kong from reaching a fruit at the end. Each Gōrumondo takes a different number of times to defeat. The first one appears in Massive Canyon, and it takes five hits to defeat. Another one appears in Ancient Foundry, and it takes seven hits to defeat. A third Gōrumondo appears in Magma Coliseum.
Gōrumondo attack by curling into a ball and rolling toward Donkey Kong. When they stop, Donkey Kong can use the Sound Wave Attack, causing him to engage a fallen Gōrumondo. He first kicks it into the air, and then, after hitting it back into the air a number of times, punches it into submission. Once defeated, they leave behind five beats.
