The player can create their own strategy to complete the level. Plant Sunflowers and Twin Sunflowers for sun. Remember to collect as much sun as you can to plant offensive plants. There are no plants that can bypass graves, so using Bonk Choy is a good choice for killing the first zombies. Also watch out for Explorer Zombies, don't use Bonk Choy to attack them. Use the Peashooters, Repeaters and Threepeaters to defeat them.
