Mold

Mold is a hazard that can threaten the lives of Pikmin and turn them against their leaders. Additionally, mold can alter fauna and flora it touches, and revive dead matter.

In Pikmin: Neo
Mold appears in Pikmin: Neo as a hazard similar to spores as it is an infectious powdery substance. It takes the form of a green, mossy substance, but can appear as a thick green mist when airborne. Mold is far more infectious than spores, which can only turn Pikmin into Mushroom Pikmin and has temporary effects, as it can turn Pikmin into Moldmin as well as infect wildlife. Mold slowly drains the life force of creatures that come into close contact with it, and upon dying, those creatures are revived by the mold, adopt a zombie-like appearance, and gain a uniquely gray health wheel. Only Cleaner Pikmin can destroy mold and cleanse it from infected Pikmin.

In Pikmin: Other Frontier
Mold is a hazard in Pikmin: Other Frontier that takes the form of a moss-green powdery substance that affects all Pikmin except Cleaner Pikmin. Mold is comparable to poison in that it is emitted from certain destructible obstacles, although mold vents are black rather than tan, although unlike poison, which mainly suffocates Pikmin, mold makes Pikmin hostile and converts them into Moldmin. Some enemies that wield mold appear to be under its control, although others appear to have control over it.
