Zombies Enemy: Regular Zombie, Conehead Zombie, Ducky Tube Zombie, Balloon Zombie
Recommended Plants: Sunshroom, Sunflower, Puff Shroom, Fume Shroom, Sea Shroom, Lily Pad, Plantern, Cactuc Plant, Spike Weed
Reward: Blover Plant
This stage introduces a new balloon zombie. The balloon zombie can bypass all of your defending zombies. The only way to counter them is by using the cactus plant which can pop its balloon. The safest bet is to plant a cactus plant on all the lanes so that they can pop the balloons as soon as they appear.
Spam the puff shroom and sea shroom while building up your sun production. This stage acts more or less a practice round for you to utilize your cactus plants. You should be able to beat the stage without much effort.
