Enemy Zombies: Regular, Conehead, Pole Vault
Reward: Chomper Plant
This stage is very similar to the one before. The only difference is that this level lasts a litte longer than the previous levels.
In addition, you can start to use the snow pea plant that you obtained in the last level. You only need 1 row of snow pea to get the benefit of slowed down zombies. This is mainly because the non effected zombies walk a little faster which would pass the affected zombies.
Like the last stage, place a couple rows of pea shooters plus 1 row of snow pea to pass the stage easily.
