Tunneller Zombie

Sorry for no picture. I just have no idea how it should look like :( Could someone make one for me?

Summary
He takes 23 NDS and when he gets onto a second tile he will dig down and make a tunnel for zombies to travel though to avoid defences. The tunneler will make an exit for the zombies when one of these happen.
 * He dies.
 * His shovel gets stolen.
 * He reaches a sunflower.
 * He reaches the end of the lawn.

Stratagey
Do basicly the same thing as what you do with a digger zombie.
