Wateenah

Wateenah is a "plant" in '78 Zombie War. It is unlocked in Day 15, the level before the last level of the Day Side. Since it is an instant-use plant, it can't have Plant Food.

Usage
After planting, it will melt and turn into water. Her water will slip out zombies out of the screen and the water will dry.

Trivia

 * Wateenah is an portmanteau of Water and Sheenah.
