Venom Weed is a plant species found in Metroid Prime and Metroid Prime 2: Echoes. It is related to normal Tangle Weed, with the exception of their varying coloration (scarlet in Prime, and purple in Echoes) and poisonous nature. Whereas Tangle Weed is merely an inconvenience, Venom Weed is truly dangerous, depleting Samus' health if she wanders into it. It is found in the Chozo Ruins and Tallon Overworld in Metroid Prime and Torvus Bog, Dark Torvus, and Sky Temple Grounds in Metroid Prime 2: Echoes.
