The Puffstorm is a boss found in The Lost Chasm. It is a cloud of purple gas with yellow antennae hovering above it. It is a normal Puffstool, that has mutated, when it was struck by a chemical bomb. The mutation has gave it enhanced abilities, such as duplication, the ability to shoot out fire, ice, water etc., and it can summon other Sporovids. If Pikmin get to close, they will be possessed by the spore cloud, and become Mushroom Pikmin. The antennae of this creature has not undergone any transformation, but can still shoot out electrical energy balls. This has led to speculation, that it may be a new species of Sporovid, transformed, but this can not be confirmed. When defeated, the creature implodes, leaving nothing. Because of this, the biology of this creature, is a complete mystery.
