The Red Onion is the nest of the Red Pikmin. It it the first Onion to be discovered in both games. In Pikmin 1, the Red Onion is found at The Impact Site, dormant in the ground not far from where the S.S. Dolphin crashed. Once awakened, it will release a single Red Pikmin seed which Olimar can use to harvest nearby red Pellet Posies and spawn enough Pikmin to retrieve the Main Engine. In Pikmin 2, this Onion can be found in the Valley of Repose.
