The Lawn of the Dead quest chain is a series of 5 quests that begin and end with Brazie the Botanist in Hillsbrad Foothills. Each quest zones the player to an instanced area, and allows them to play a game within the game, based on the popular internet game "Plants vs. Zombies". The interface changes giving you a new toolbar that allows you to use seeds. Once the final quest is completed, the player receives Brazie's Sunflower Seeds which teaches the player how to summon a new Cataclysm companion called the Singing Sunflower or Brazie's Sunflower.
The first quest begins with a simple explanation of how the game works. You get Spitter seeds and solar power orbs. Zombies come down the center row and your spitters have to kill them before they destroy the flowers you've planted. If a Zombie reaches the house on the other side of the map, "Zombies eat your brains," and you fail the quest. Over the course of the next three quests, you gain 5 additional seeds that include Sunflower, Freezya, Rocknut, Strangling Vine, and Pumpkin Bomb seeds. Each have their own function and strategy which you must use to aid you on the final quest, .
