Hi I'm posting about the Grave Buster. Grave Busters remove Graves and Zombie Gravestones, letting the player plant where they could not previously and also reducing the amount of zombies that emerge from the ground during the final wave. Simply plant a Grave Buster on a Grave to remove it. Be careful, however, as zombies can eat the Grave Buster while it is working - it takes about 4.5 seconds to remove a grave, and if it is destroyed, the process has to be started over again. Once the Grave Buster removes a grave the player is awarded with a silver coin, or less often, a gold coin, a diamond, a Chocolate or a Zen Garden Plant. It can only be planted on graves. Despite its fearsome appearance, it has no ability to defend itself.
