Main Strategy
For starters, buy a rake, the rake will appear in a random lane. Plant 4 Sunflowers first. When a zombie appears, the rake will kill that zombie. For the next Zombie, plant a Kernel-pult once you get enough sun. If there's a Conehead Zombie appear, plant a Melon-pult with a Pumpkin. When you done the 1st/2nd flag, make sure you preview your lawn first so you can upgrade some of the plants! If there's a Digger Zombie, the best way to kill it is a Jalapeno when it's still digging under the ground. When the Gargantuar appears, use an Instant-kill plant, then a Jalapeno to kill both the Gargantuar and the Imp. Then upgrade your Melon-pults to Winter Melons.
