Squash

The Squash is a one-time use plant that attacks zombies in an adjacent tile by smooshing them.

Usage
Planting a Squash costs 50 Sun. When planted it waits until an offending zombie is next to it [left or right], it then jumps on it, destroying itself and dealing a large amount of damage to the zombie.

Strategy
The Squash is an OK plant to use against that one zombie that is too strong for the current defense or that managed to sneak through. However, plants slots are generally too valuable for this plant to be of much use
