Water Chestnut

Water Chestnut is an aquatic plant. When planted, it will act as defense for you and takes 82 bites to be eaten, so a slightly stronger Wall- nut.

Trivia

 * It is based off of the real plant, the water chestnut, and "water", which implies its aquatic ability.
 * It was adopted here.
 * The wave it creates during its Plant Food Affect can knock down Surfer Zombies and make them walk in the water.
