Two LSD Mushroom Monsters shown in a Superjail poster.

The LSD Mushroom Monsters are large, man-eating mushrooms with eyes and sharp teeth. However, some have feet. They appear in the episode "Don't Be A Negaton".

The LSD Mushroom Monsters appear when Jared is running with fear. The monsters laugh at him, and one manages to grab him and throw him into the D.L. Diamond Spider's web.

At the end of the episode, The Galactoids fly in and blast away all of the monsters.
