Chomper

The Chomper is a multi-use one-shot-kill plant.

Usage
The Chomper can kill any zombies other than a Gargantaur in one bite. It will spend about 40 seconds chewing afterwards.

Strategy
The chomper has a range of two squares, so it can eat a zombie on the other side of a Wall-nut. Like all high-damage plants, it's best against tough zombies.
