The Awakening Wood level is the second level that can only be accessed if you get the Spherical Atlas from the Emergence Cave cavern in the Valley of Repose. It was actually The Forest of Hope in the original Pikmin game. Some areas became submerged while others are not submerged anymore and more obstacles can be found, also the tin cans disappeared. Otherwise, the Awakening Wood level has four caves, seven treasures, and many foes. This is where you'll meet Blue Pikmin.
