The Hypno-shroom is a single-use mushroom that causes the next zombie biting it to turn around and attack other zombies. It is the ultimate passive-aggressive plant, for those who dislike all that messy killing. The Hypno-shroom has swirly eyes, suggesting that it hypnotizes. It seems to be based of various psychedelic mushrooms, which affects the thinking of the brain. It makes the zombies turn into a pink/purple color.
