Zombies Enemy: Regular Zombie, Conehead Zombie, Screen Door Zombie
Recommended Plants: Sun-shroom, Sunflower, Puff-Shroom, Fume Shroom, Repeater, Wall-Nut, Chomper
Reward: Grave Buster
In this stage, you will encounter a new zombie – the screen door zombie. The best way to kill the screen door zombies are using your stacked fume shrooms or use chompers to take them out.
Start the stage by setting up the usual 5~6 sun-shroom then switch over to sunflowers. You can either use a couple of repeaters + chomper + wall-nut as your front line defense. Your other defense option is to setup a couple rows of fume shrooms and they will take out zombies super easily.
