Wolfbane

Wolfbane is a smelly plant with thorns that is capable of inducing the condition of lycanthropy in Smurfs in the EMPATH: The Luckiest Smurf story series. The first known victim of wolfbane was Crazy Smurf, who was scratched by the plant when he was a Smurfling and was soon turned into a weresmurf. Although Papa Smurf cured his condition, a lingering side effect was that it induced clincal lycanthropy in Crazy, causing him to bay at the full moon every month. A later victim was Brainy, who was eventually caught by a human showmaster before the Smurfs freed him and cured him.
