Zombies Enemy: Regular Zombie, Conehead Zombie, Catapult Zombie, Bungee Zombie (Drop Off Only)
Recommended Plants: Sunflower, Twin Sunflower, Flower Pot, Torchwood, Repeater, Potato Mine, Pumpkin, Cherry Bomb, Cabbage Pult
Reward: Umbrella Leaf Plant
This is a pretty easy level once you get your fire power ready. Setup the sun flower production. Setup double and triple row repeaters toward the end. Place the torchwood infront of your repeaters, and watch the fire balls bring hell to all the zombies.
Although the catapult can deal some damage to your plants, but your backrow sun flowers are really dispensable. However, if you wish, you can instant kill those catapults with cherry bombs as well. Although the chances are that you will not need to once you setup your fireball attacking squad.
Lastly, because the bungee zombie will drop off some zombies during the last wave, you can consider placing some cabbage pult at the far left.
