Yellow Onion

The Yellow Onion is the home of the Yellow Pikmin and is the second Onion the player will come across in both games. In Pikmin 1, it is found dormant in The Forest of Hope amidst several yellow Pellet Posies and free-standing yellow pellets. In Pikmin 2, the Yellow Onion is located in the Perplexing Pool behind a poison gate, so White Pikmin are required to reach it. There are a few yellow Pellet Posies nearby which will not regrow once they've been harvested.
