Blue Onion

The blue onion is where you store your blue pikmin. In Pikmin 2 the blue onion is behind an electric gate in the Awakening Woods. You can get to it by taking your yellow pikmin to the ledge in front of the gate and throwing them up. Then you can go through the water as Olimar or Louie and whistle the yellow Pikmin, then go around and break down the gate. Then, when they are finished, leave them ther and get the Pikmin. Then you can defeat the wogpoles and the pellet posies and take them back to get more Pikmin.
