Combat Cavern is the 6th accessable area in Pikmin: The War of the Pikmin Planet. Much like the Forest Navel in Pikmin, this area is almost entirely underground, with a small aboveground area for the ship to land on. Instead of having four caves and one dark cave like past areas, this area only has 2 normal caves and one dark cave. This is because the caves are scaled up in difficulty and length compared to former caves.
- Combat Cavern is where Ferinus used to live before the Black Pikmin kidnapped him.
