A vengeance tree is a species of tree most noteworthy for it's behaviour of defending itself against harm. It does this by dropping large red hanging pods from its branches onto its attacker below. The pods contain an irritant that causes severe rashes on the skin, and possible serious damage to the eyes. Additionally, the juice in the pods smells similar to rotting meat, attracting large predators to come and attack whatever was harming the tree. These predators include giant wasps.
