Puffstool

The Puffstool was a bizarre but formidable enemy from the first Pikmin game. Residing only in The Forest Navel's darkest corner, it used spores to turn the Pikmin against Captain Olimar. By attacking only the yellow part of the creature and calling Pikmin back before the spores could take control, Captain Olimar was able to defeat the puffstool and carry back the ship part it had taken, the Omega Stabilizer. It was a necessary part in order to escape the Distant Planet.
