If you eat a Toxic Mushroom, you get some sort of super power. The first sign of you eating it, is your stomach starts to hurt after 5 minutes of it being eaten. The second sign is if you get intoxicated randomly. It has a bright color so that you could know its not good to eat. Apparently, some people still eat it. Fistgee was one of the victims of it. His powers were used for good cause whatsoever.
