Dumdum

A dumdum is a type of flower that grows wild in the Smurf Forest in the EMPATH: The Luckiest Smurf story series. According to Papa Smurf's books on plants, dumdums cause whoever inhales its pollen to act as if they're totally stupid. Dumdums hardly affect Clumsy or Dimwitty since they are both of low intelligence and very klutzy.
