This level is harder, due to it having more zombies than the previous ones. 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. If you used it before the Gargantuar was unleashed, use the two Potato Mines on it. If you don't have those either, it is recommended to reset the level.
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.
