This article or section presents information pertaining to Pikspore, a fanon game created by DrTapeworm.
The Dirty Realm is probably the second cave entered in Cliffside Meadow. Upon discovering the cave, the ship angrily refuses to enter due to intense readings of dirt and mud. Intense seems to be an understatement, as this may very well be the filthiest cavern in Pikspore. The main gimmick of the cave is the brown mud, which sticks to Pikmins' skin and hampers their movement, and black mud, which is also harmless but gets your Pikmin stuck. To get them out, use the whistle as if they were drowning in water and they should squirm back onto dry land. Black Pikmin walk through them without trouble, however.
