The Puffstool is an enemy in Pikmin 1 that appeared to be a huge walking fungus. It had a red capped mushroom head, and a tender yellow torso that was vulnerable. Not much is scientificaly known of it, but minimal details are supplied. It would run from your Pikmin and you had to swarm the feet of it to knock it over and it would land on its head. You then would throw Pikmin to attack it and then wait. If you finished it off, great, if not, it will jump back up and emit a strange gas that will affect your Pikmin, their heads will be replaced with moshrooms, and they turn purple. These Pikmin are known infaously as Mushroom Pikmin.
