Sublevel

In Pikmin 2, there are 14 caves, which all consist of a number of sublevels. Upon entering the cave, you start on the first sublevel with your Pikmin; to progress, you must find the cave that leads down to the next sublevel. A geyser is always found on the final floor, often along with a boss, though geysers are also found at intervals throughout longer and more challenging caves, such as Subterranean Complex and Submerged Castle. These allow you to return to the surface of the Pikmin Planet.
