The mature form of Swampweeds, Stinkweeds emit the same deadly poison in greater quantities.
When alerted to the Kid's presence, Stinkweeds emit clouds of toxic gas that float their target.
When destroyed, Stinkweeds immediately release 5-6 clouds that move outward, lingering for several seconds.
There is rarer orange varient of Stinkweed that launches balls of gas at the Kid. These balls can be blocked by the Bullhead Shield, but move much faster and can go over terrain, unlike their cloud counterparts.
