The Onions are the nests of the Pikmin. Olimar named them so

the Onions land at the start of each day, there are concentric
circles on the ground, which are never referred to in-game.
Three stilt-like legs suspend the Onions out of the reach of

to either Red, Yellow or Blue Pikmin, and only one of each has
ever been seen. Subterranean Pikmin species such as Purple
Pikmin, White Pikmin and Bulbmin do not have Onions, or at least

Onion, which in turn pro
