The Perplexing Pool is a location in the GameCube game Pikmin 2. This is the third location that Captain Olimar and Louie can travel to. It is also the place where the Yellow Pikmin are first located in the game. This area has a pronounced number of lakes, with quite a large area of the level submerged at both ends. There are four caves and seven treasures above ground.
The area is noted to bear a number of striking resemblances to The Distant Spring in Pikmin, for which reason it be confidently considered to be the same area of the Pikmin Planet. Despite the similarities, there are some differences: for example, small islands are missing in the later version, and obstacles such as bridges and gates have been changed.
