Vemon Drool is a special move that appears in Super Mario RPG: Legend of the Seven Stars. It can be used by a few enemies and bosses in the game.
When Venom Drool is used, a large bubble heads toward the target and bursts open releasing poison on them. Of course, this poisons whoever is hit by this attack (unless they are wearing an item such as a Safety Pin). This move is similar in appearance to Viro Plasm.
