Onion

The Onion is a vital part of Pikmin reproduction and safety. All types of Pikmin are stored in their respective motherships, referred to as "Onions", for safety after sunset, as they are vulnerable to nocturnal predators. The Onions play a vital role in Pikmin reproduction: when any food, such as prey or pellets, is delivered to an Onion, it propagates seeds, which grow and are plucked from the ground as fully developed Pikmin. An Onion serves as an incubator for all Pikmin of its respective color, housing the Pikmin. The Onions travel alongside Olimar as he flies to different locations on the planet PNF-404.
