Mossteroid

Mossteroid hurls heavy, mossy rocks at zombies that deal tile damage, while alternately defending.

Usage
While dealing tile damage, and also defending, he would be great for this world's Brain Busters, except High Gravity.

Plant Food
Mossteroid makes a meteor shower of smaller Mossteroids, but when they land, they explode in a 1 by 3 area.

Strategies
Mossteroid, being offensive and defensive, and having half health as a Wall-nut, and the same strength of Melon-Pult, it's recharge and it's rate of fire is not worth the wait. Aloe can help Mossteroid out when he's been munched on, giving a much longer life-span. Since it deals tile damage, huge groups of Imps, and Basic Zombies cannot overwhelm it.
