Darkshroom

The Darkshroom Plant is a plant found in certain areas in Pikmin: Revenge of the Darkfreeze. It is not dangerous, but it can be very annoying as it can infect Pikmin with Darkshroom.

Darkshroom
Sometimes, when a Pikmin goes near Darkshroom plant, the plant will release spores, which will infect Pikmin with a disease called Darkshroom. It is not lethal, but when infected, Pikmin will instantly be turned to leaf Pikmin, turn a darker shade, have white spots on its stem, and will wobble and be weaker in combat. The disease can be cured with nectar.

Trivia

 * It is believed that both plant and disease was a failed experiment by the Darkfreeze to exterminate Pikmin.
