Poison Dryalid

The Poison Dryalid is a cactus that only grows in the Kohenyu Graveyard on the Floating Island. It has purple flowers, and can spray a blue mist or powder (possibly spores). This mist is a potent poison, capable of causing hallucinations, unconsciousness and sometimes even death. When Knuckles travelled to the Kohenyu Graveyard to find a replacement Master Emerald, he was sprayed in the face, causing immediate grogginess and difficulty breathing. He also wondered whether his seeing the Spirit of the Herd was caused by the hallucinogen, although this proved not to be the case. Although Knuckles eventually fell unconscious, his great strength allowed him to eventually recover.
