Underground Device

Underground Device is the final cave in Volcanic Wastes. It is a derelict supercomputer built by an ancient civilization as part of a long-abandoned project. Though old and full of creatures, much of the machinery is still active, posing an electrical threat to any but Yellow Pikmin. One of the main gimmicks is the switches that open gates. The cave has nine sublevels and sixteen treasures, which are scattered around the cave.
