Puffstool

Puffstool (ポワール) is a minish-sized monster that is quite easy to defeat, although it often lies within the dust that slows Minish Link down. Puffstools normally have red caps, and are near-invincible in this state. When Link uses the Gust Jar on it, it turns gray and with a few sword slashes it should be defeated. Puffstools appear in a variety of places, like dungeons and caves, often hiding in the dust for a surprise attack. When they shake, their spores accumulate as more dust, which can be cleared with the Gust Jar.

Trivia
The Puffstool may be based on a Pikmin enemy of the same name.
