Fire Bow Zombie

The Fire Bow Zombie is a Zombie with a, say, flaming Bow in his hands. He has 30 health.

Overview
He doesn't exactly attack your house, but he is an expert is destroying defenses. When he reaches the 6th column, he crouches down, lights his arrow, and shoots it straight into your 3rd row. The fire quickly burns up the plant, which, if not dug up, the fire spreads to the plant in front and back of the plant. And goes on as a chain reaction. Once he has finished shooting, he goes back to the 9th column, only to aim at your plants.. AGAIN!

Note that Blovers put out the fire and Umbrella Leaf plants can stop the fire burning- though they still take damage anyway.
