Manchineel

Manchineel is found in [insert game here], obtained in [insert world here] in [insert level here].

Overview
Whenever a zombie comes into a 4x4 radius to Manchineel, he will release a toxic gas and then disappear, shrouding that area in a very damaging cloud of poison that lasts for 10 seconds. Any plants planted in the gas cloud will instantly die.

Because Manchineel is so poisonous, any plant in a 3x3 radius of Manchineel will take damage. Only plants that either are resistant to poison or are poisonous themselves can stand Manchineel's poison.

Strategy
If you consider using Manchineel, do NOT use them where you need plants like Flower Pots or Lily Pads, because Manchineel will damage those too.

When you use them, make sure there isn't a plant nearby, and don't plant anything in the gas cloud.
