Toxic Gloom-shroom is a new spawnable plant in Plants vs. Zombies: Garden Warfare 2 which can be spawned in pots during Garden Ops, Gnome Bomb, and Gardens & Graveyards as well as in the Backyard Battleground. It attacks zombies by spraying a close-range burst of toxic gas around itself that deals 20 damage and poison nearby zombies. Its attack is called Toxic Mist.
CLOSE RANGE: TOXIC
Voted most toxic plant 3 years running. He ain't happy about it though.
