The Evil Mushroom is a semi-sentient plant similar to the Mad Cactus and the Haunted Tree. It appears as a large blue mushroom. Holes in its front create a simple face consisting of two eyes and a mouth—the eyes are slightly mismatched, and the mouth has small protrusions resembling teeth.
Much like its fellow Killer Plants (Haunted Trees and Mad Cactuses), the Evil Mushroom is a low to moderate threat on its own, having several elemental weaknesses, no resistances, and one immunity.
In addition to its elemental weaknesses, the Evil Mushroom can be largely neutralized as a threat by inflicting Syphon upon it. While Syphoned, it can only use its basic melee attack, making it much more manageable.
