Giant Kosha is the final mini-boss found in Donkey Kong 64. It is the mini-boss of Crystal Caves. The giant Kosha is stationary on the top floor of the cave. It attacks by smashing its club on the ceiling, which makes boulders rain down on the Kongs. It also creates earthquakes with its club. In order to defeat it, one of the Kongs must travel to the top floor while avoiding falling boulders and earthquakes. Once they reach the top, they must position themselves in front of the mini-boss. Once there, they must either play their musical instrument, use the shock wave attack, or throw an Orange while the giant Kosha is vulnerable.
Upon being defeated, the giant Kosha does not respawn, which permanently ends the avalanches that it makes.
