The third dungeon in the Cloaking Field. It is a cave dungeon. It is located in the maze at the back of the Cloaking Bush. This confusing maze is filled with dangerous enemies like Radiagoolixes and Pump Groinks. Because of this, blue and yellow pikmin are nessecary to get in there. The cave is mostly completely dark, but some levels in its second half are outdoors-like and light out. The cave gets its name from the large amount of yellow and plain reptiums, and its boss.
