Grassy Zombie

Overview
The Grassy Zombie is stronger than a typical zombie, but weaker than a conehead. After taking 5 hits from straight attacks (or a hit from any fire based attack), the foliage on its torso breaks apart, releasing 2 Grassy Imps on nearby lanes (fire attack prevents imps). Then, after another 10 hits (11-14 if fire was used earlier and 15 if using only catapults), the zombie loses the dirt slab on its head, making it look like a normal zombie (kind of). Another 10 hits finishes it off.

Strategy
It is recommended to use either fire, lobbed, or instakill attacks. Instakills, however, should be used as a last resort.

Fire Strategy
Fire plants such as Fire Peashooter or Snapdragon will instantly break through the foliage, and prevent the Grass Imps from spawning. This really helps to bring down the zombie numbers. However, Pepper-pults won't have this effect, as they are lob-shot plants.

Catapult Strategy
Lob-shot plants such as the Cabbage-pult or Melon-pult completely avoid the foliage as they aim for the head of the zombie.

Bad Strategies

 * Blovers and Hurrikales - Blovers/Hurrikales will blow away foliage, instantly spawning imps.
 * Primal Peashooters - Primal Peashooters' rock-like peas break the foliage, instantly spawning imps.
 * Hypno-shrooms (no plant food) - Zombies will eat the foliage first, releasing un-hypnotized imps.
 * Chompers and Toadstools - Eating the Grassy Zombie will release its imps near the column that the Chomper/Toadstool is in.
 * Repeaters and Pea Pods (plant food) - Giant peas while killing Grassy Zombies in one hit, release the imps. However, placing a Torchwood in front solves this dilemma.
 * Fume-shrooms (plant food) - Like with Blovers, this blows away foliage, releasing the imps.
