This level is harder, due to more zombies than usual. But with the purple vase that always contains a Vase Gargantuar, this level is easier than the first game. This notifies the player where the Vase Gargantuar will be.
Break the vases from the rightmost column to get a few Repeaters.
Two Potato Mines here should be put on the lane that has the purple vase.
If you get a Plant Food, save it until you are in danger.
Only break the purple vase when the lawn runs out of vases. The purple vase always contains a Vase Gargantuar, use the Plant Food to defeat it.
