Relaxing River

Relaxing River is the second area you unlock in Pikmin 3: Dark Matter's Rising. Blue Pikmin, White Pikmin, Aura Pikmin, and Pink Pikmin are discovered here. It is a damp swamp-like area with a river flowing through it, making a "tile pool" in the corner.

Caves

 * White Flower Garden
 * Tile Pool
 * Aura Den
 * Forgotten Old Castle

Trivia

 * It is actually side-by-side to the Perplexing Pool in Pikmin 2. The "tile pool" is next to the cave "Shower Room" in Pikmin 2.
