Grave Buster

Grave Busters remove graves and zombie gravestones, letting the player plant where they could not previously, and also stopping zombies from emerging from the ground during the final wave. The player must simply plant a Grave Buster on a grave to remove it.They should be careful, however, as zombies can eat the Grave Buster while it is working - it takes about 4.5 seconds to destroy a grave, and if it is destroyed, the process has to be started over again. Once the Grave Buster has finished eating the graves, the player will be rewarded with money, chocolate, or a Zen Garden plant. It can only be planted on graves.

Standard Levels
Only select the Grave Buster on night levels (even though it isn't a nocturnal plant, as proved by Versus Mode) when you can see the graveyard in the background, as graves never appear on the roof, the backyard nor in the pool. Which graves you choose to remove first depends entirely on your defensive strategy. Usually, getting rid of the leftmost ones first is a good idea, as is evening out the number of graves in the rows. Removing graves from the places you need to put a specific plant (such as a Wall-nut or Spikeweed) is also a good plan. Be careful when you plant Grave Busters, however, as they can be eaten by zombies. It is a good idea to plant them before a huge wave of zombies comes. It is possible to defeat Whack a Zombie without it though.

You might want to get rid of all the graves when you have sun to spare, and try to do it before the final wave. If you haven't gotten rid of them all by the end of a level (before you click on the item), zombies will come out depending on which types and if there are still graves left you can continue to destroy them as long as you have sun, you will still be rewarded with coins or a chocolate or even a present.

Whack a Zombie
Grave Busters are almost essential in the mini-game Whack a Zombie. If they are not planted, the zombies will probably overwhelm you near the final wave, as there will be a huge number of Graves, each rapidly spitting out zombies. At the final wave, there will be a huge number of zombies, and you will probably lose if you have a lawn mower and Potato Mine-less row. Also, if a grave has a Grave Buster on it, it will not produce zombies (unless the Grave Buster is eaten). One of the best times to plant Grave Busters is when there is a lull in zombies coming out of graves, but you should try to plant them at other times as well. This is because one or more new grave appears during each lull, and so if you do not plant them at any other time the amount of graves will never decrease (at least not until the level is over).

The best idea is to plant Grave Busters on the graves farthest to the left, slowly taking care of the most dangerously-placed ones. You may also want to plant Potato Mines in front of the lawn mowers in case a grave near your house releases a zombie and you can't reach it in time. You can plant more in when there are no more zombies, until you can't plant anymore. You can win this mini-game without using it, though.

Versus Mode
In Versus Mode, Grave Busters play a large role in destroying the zombie gravestones the zombie side must create in order to produce brains. They work just like they would on a normal grave, but there is no coin produced when they destroy one. Grave Busters have a very slow recharge in Versus Mode. Your opponent could summon a zombie to eat, crush, bomb or steal the Grave Buster, so be careful.
