Zombies Enemy: Regular, Conehead, Ducky Tube, Zomboni, Buckethead, Snorkel
Recommended Plants: Sunflower, Lily Pad, Potato Mine, Wallnut, Cherry Bomb, Snow Pea, Spikeweed, Threepeater, Repeater
Start the stage with the standard sunflower + potato mine combo. Then move on to plant snow peas with threepeater defense, repeaters on the side. After the first flag, you want to place a couple spikeweeds to take down Zombonis when they appear.
Setup the wallnut with lily pads along the center lanes to defend against snorkel zombies and “surprise” attacks that come out of the water. By second and third flag, you should have a healthy defense of spikeweeds to not have any trouble passing the stage.
