Puffstool
Puffstool is a 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 invincible in this state. When Link uses the Gust Jar on it, it turns grey and with a few sword slashes it should be done. 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.
