WoW: When Ghouls Attack: Peacebloom vs. Ghouls Mini-game Guide

Peacebloom vs. Ghouls is a brand new mini-game implemented after the Cataclysm expansion. Based off the wildly popular Plants vs. Zombies game developed by PopCap Games, Peacebloom vs. Ghouls manages to bring all of the zombie killing fun into World of Warcraft. Players will meet Brazie the Botanist who has a rather unusual problem, waves of Undead are attacking his farmstead. It will be your job to defend the farm (and your brains) against the incoming waves of Undead using only the aid of various types of plants.

Learn more about the mini-game below:

This super fun mini-game can be found at the Brazie Farmstead, a quaint little farm south-east of the Dalaran Crater. For those that prefer coordinates The Brazie Farmstead is located at 33.5, 48.4. You will know you have reached the Farmstead by the smiling sunflowers and ominous green clouds just outside the door.

Mini-games are fun, this one especially so, what with defeating brain eating Undead and all but really what do you get out of it?

Not only will players who complete this mini-game gain all the gold (and possible experience) from each quest, but when the final quest is completed players will be presented with Brazie’s Sunflower Seeds, and allow the player to choose between Brazie’s Plant Light or Botanist’s Britches. Even more exciting, however, is that players will also be awarded ….


That’s right ladies and gentlemen if you manage to defeat the evil final boss and stop the invading Undead you will get the much sought after Singing Sunflower. Modeled after the Sunflowers that appear in the original Plants vs. Zombies game this pet not only looks cool, but also will entertain it’s owner by occasionally singing a line or two from the PvZ theme song complete with musical notes above it’s head.

So you’ve reached the Farmstead and you’re standing outside wondering if the happy looking sunflowers are really plotting your demise or not (the answer to which is probably a resounding yes, plants should really never be THAT happy), but how do you get this party started? To get started speak to Brazie the Botanist, who is a rather ugly looking Goblin sporting very Druidesque gear who can be found standing just outside the door to the farm house, between the creepy sunflowers. Brazie will offer you a quest and once accepted the mini-game will begin.

*It should be noted that once you have completed a quest in the quest line you cannot go back and complete it again, and once the entire quest line is complete you will no longer be able to play the mini-game.*

Before you begin playing it may be a good idea to get a better understanding of the mini-game basics:


  • 1. The House
  • 2. The Playing Field
  • 3. Fertilize-O-Tron 2000s
  • 4. Ghoul Spawn Point
  • 5. Plants Bar
  • 6. Solar Power Gauge
  • 7. Progress Meter

The House
Defend this at all costs against the incoming waves of invaders. Seriously, if you let even a single enemy slip past your defenses, not only will you fail the quest at hand, but the enemy in question will not hesitate to rush inside and eat whatever warm brains he can find. Brains are like filet mignon to these dudes, so they don’t mess around.

The Playing Field

The playing Field is where all the action happens and is essentially a 5x8 grid consisting of 5 separate lanes with each lane containing 8 individual squares. At one end of the Field is the farm house and at the other the enemy spawn point. Here you will line up your defenses and hopefully defeat the oncoming waves of enemies.

Fertilize-O-Tron 2000s
The Fertilize-O- Tron 2000s are your last line of defense. Located just outside the farm house these machines look like they were borrowed from the Forsaken. While ideally you never want to have to rely on these if an enemy does reach one of these engines of destruction the Fertilize-o-Tron will kick into action and promptly mow down the offending invader and any other enemy in the lane. The Fertilize-O-Tron will not respawn once it has been activated leaving the lane it came from especially vulnerable.

Ghoul Spawn Point

Undead of all types will spawn in this location at the end of one of the five rows. Once spawned, they will make a beeline for your house straight down the lane they originally spawned in front of. Your foes will always follow a straight path and will never diverge into other lanes.

Plants Bar

Here you will find all the plants and abilities needed to complete the various quest levels.You will begin with a single plant (the Spitter) however, things will get more complicated as you progress with more plants and abilities being added as you go.

When the bar has all your plants and abilities on it the icons are from left to right:

  1. Sunflower
  2. Spitter
  3. Freezya
  4. Rocknut
  5. Strangler Vine
  6. Pumpkin Bomb

Solar Power Gauge
The Solar Power Gauge is where you can see the total amount of Solar Power you have managed to collect. Solar Power comes from bright yellow balls that will randomly fall on the Playing Field as you play. To collect Solar Power simply hover your mouse over one of the yellow balls and right click. As you collect Solar Power the Gauge will fill up by 5% with each ball.

Progress Meter
The Progress Meter will appear as soon as you begin a level. As you defeat each wave of Undead, the Progress Meter will fill up. Once the Progress Meter is full, the stage is complete and you can rest easy, at least for a little while.

Now that you understand the basics of the interface it’s time to move on to those crazy characters; the Plants!


The plants in this mini-game are your saving grace and will be almost all that stand between you and the invaders. While you only begin the game with 1 single plant you will eventually gain access to 6 different plants. Each plant  costs a specific amount of solar power to use and must be placed in one of the individual squares in one of the five lanes.

Spits poison at oncoming enemies in the lane it is placed in causing 50 damage.

Produces one extra Solar Power ball each cycle.

HP: 968
Solar Power Cost: 20
Assaults oncoming enemies with a freezing attack that temporarily slows down any enemy it hits, but only causes 35 damage.

While this unit won’t attack, it does act as a physical barrier against any enemies in the lane it is placed in. No enemies will be able to bypass the Rocknut until its hit points are gone.

This plant will grab the nearest enemy and trap it then slowly damage it until it dies. Unlike the other plants the Strangler Vine can damage enemies when on an adjacent square. Strangler Vines can NOT trap Aberrations, Abominations or Warden Stillwater.

When placed on a square, this plant will explode doing huge amounts of damage to all enemies near it. This plant is the most effective weapon to use against Warden Stillwater.
So we’ve covered the good guys, now lets move on to those brain eating invaders; the Ghouls.


The most common of the Undead, these units move slowly and die quickly.

Moving move quickly than Zombies, Ghouls also have more HP and also do more damage. Using Rocknuts to stop them, or Freezya plants to slow them down is a very good idea.

This unit has quite a bit of HP making it the hardest common unit to kill, not to mention that it can take out your plants quickly. Trap, slow, or blow up these Undead before they cause considerable damage.

While very slow, Abominaions can be very dangerous. These units do tons of damage and are hard to kill. Use Rocknuts to stop them and Pumpkin Bombs when possible to take them out.

Used as a primary defense by Warden Stillwater (the final boss) these units will block Spitter attacks and prevent you from doing damage to the Warden. Use Strangler Vines to get rid of these nuisances quickly and effectively.

This is the final boss in the mini-game, the big kahuna if you will. Until all the other Undead before him are defeated, Warden Stillwater will not attempt to cross the field. Instead he will wander back and forth in the Undead Spawning Zone tossing vials of fertilizer on your plants which will automatically cause them to wither and die after 30 seconds. Warden Stillwater’s primary mode of defense will be in the form of Obelisks detailed above. Pumpkin Bombs are currently the most effective method of killing this boss.

To complete the Plants vs. Ghouls mini-game players will need to complete five separate quests:

  • [20] Basic Botany (Survive a Massive Wave of Zombies)
  • [20] Flower Power (Survive a Massive Wave of Zombies)
  • [20] Ghouls Hate My Grains (Survive Two Massive Waves of Zombies)
  • [20] Someone Setup the Pumpkin Bomb (Survive Two Massive Waves of Zombies)
  • [20] Lawn of the Dead (Defeat Warden Stillwater)
Continue reading for a complete walkthrough for each of the quests.

Basic Botany

The first quest in line is Basic Botany and it is essentially a tutorial that will teach you the basics of game play and familiarize you with the various aspects of the mini-game. You will notice that messages containing instructions on how to meet the needed goals will occasionally flash across the screen. Pay careful attention to these, otherwise you may find yourself very confused.

When this quest begins the first message you receive will instruct you to collect Solar Power and place Spitters in the center lane (designated by a patch of sunlight) to fight zombies that are sure to be coming shortly. There is no rush at this point, no Undead will appear until after you have placed your first Spitter. So take a second at this point to get comfortable with the interface.

You may have noticed by this point that glowing golden balls of light have been falling from the sky onto the Field. This is your Solar Power. As mentioned above, simply right click these orbs to collect them which will in turn fill up your Solar Power Tank by 5% with each ball collected. In case you forgot; Solar Power is what you will use to purchase various plants to defeat the oncoming Undead.

When have enough Solar Power click on the Spitter icon on your vehicle bar and place it in the first square in the center lane (3A) which is highlighted with the golden circle of sunlight. Once the Spitter is placed the first Zombie will spawn in the Undead Spawn Zone at the opposite end of the field. Your Spitter will automatically attack the Zombie as it begins to shamble towards the house. While planting a single Spitter will easily allow you to complete this level, to speed things along you can plant several more Spitters in lane 3.

After several Zombies are defeated you will be warned that a massive wave of Zombies is approaching. This warning indicated that the final stage of the battle is about to begin and the quest is close to being completed. At this point usually large numbers of Undead would spawn and descend upon wrecking quite a bit of havoc. Since this is the tutorial only 5 Zombies will spawn and attack in lane 3. Any Spitters you have planted (even only one) will easily defeat the wave of Zombies.

Once completed this mission will unlock your second plant; the Sunflower.

Flower Power

Toto, we aren’t in the tutorial anymore. The second quest in the mini-game is more intense than the first. Here you will be introduced to a second kind of enemy (Ghoul) and two new plants (the Sunflower and the Freezya). Thankfully things are still kept slightly simple as spawning enemies will only advance from rows 2, 3, and 4.

Start collecting Solar Power as soon as possible and plant 3 Sunflowers to start. Because enemies will only be spawning in lanes 2, 3, and 4 place the Sunflowers in lane 1 or 5 to prevent them from being attacked. Soon enough a Zombie will spawn and begin his quest for brains, when this happens quickly plant a Spitter in the second square of the lane the Zombie has appeared in.

After the Spitter is planted continue planting Sunflowers in lanes 1 and 5 until the first three squares in each row contain a Sunflower. Only diverge from this course if a Zombie spawns in a lane without a Spitter, if this happens quickly plant a Spitter in the second square of that lane. Eventually you will have Spitters in the second square of lanes 2, 3 and 4.

About halfway into the mission a random Zombie will drop a sack onto the field. Right click on this bag to unlock your third plant; the Freezya. You will gain access to your newly found plant right away so plant Freezyas on the first sqaures of lanes 2, 3, and 4.

At this point your field should look like this:

From this point on you will continue planting Spitters in rows 2, 3, and 4 until the quest is completed. Remember to plant Spitters in the lanes that contain the most enemies first. Once this quest is complete you will unlock the next quest and a new plant; the Rocknut.

Ghouls Hate My Grains

If you thought the second mission was intense, the action really ramps up in the third. This time around you must survive not one, but two Zombie attacks not to mention your enemies have smartened up and will now be attacking from all 5 lanes.You will also have access to two new plants, the Rocknut which you gained from completing the last mission, and Strangler Vines, which will come into play later in the mission.

When play begins you will notice that square 3E is highlighted as well as the Rocknut on your Plant Bar. Ignore this for now and instead use your first Solar Power to purchase a Sunflower which should be placed on 1A. With your next 10 Solar Power place another Sunflower on 3A. At this point your first enemy; a Ghoul should have spawned at the end of lane 3.  

Now it’s time to bust out the Rocknut by placing it on 3E to block the oncoming Ghoul. Now place another Sunflower 5A followed by a Spitter on 3D to wipe out the Ghoul trapped behind the Rocknut. After this you should continue to plant Sunflowers on 2A and 4A then move on and plant a Freezya on 3C.

At this point in the mission your field should look like this:

From here your main goal will be to fill lane B with Sunflowers, C with Freezya, and D with Spitters. Remember while it’s easy to become involved in planting do not forget to collect Solar Power as it drops or you will find yourself in a very sticky situation. Planting these Sunflowers and Freezyas will not be your only focus as Zombies and Ghouls will continue to spawn.

If you are making good time and picking up Solar Power as you should be you should have at least two Sunflowers planted before the next Zombie spawn. Plant a Spitter in the row the Zombie appears in at which point you will discover that a Ghoul has decided to make an appearance.

Delay the Ghoul by dropping a Rocknut in his path and rest on your laurels for a bit while building up some Solar Power. As soon as you have collected 20 Solar Power place a Spitter in the lane the Ghoul mentioned previously spawned in. Now plant another Sunflower then a Freezya in the same lane where the Ghoul appeared, then another Spitter in row D. With all 5 lanes now having a method of attack you can finish planting the Sunflowers and Freezyas without much distraction.

With the first Massive Wave pending, use any remaining time to place Rocknuts in row G.

Your field at this point should look much like this:

Continue to fill out the 5 squares in row G with Rocknuts, and you will hopefully easily defeat the first Massive Wave, if any Rocknuts are destroyed replace them as soon as possible. Once this wave is defeated a zombie will drop a bag on the field. Click the bag to unlock your newest ally; the Strangler Vine.

Before the final, final wave you will be focusing on the continued building of your defense. Replace any Rocknuts that are destroyed and with any remaining Solar Power set about filling rows E and F with Spitters and row H with Strangler Vines.

When the final wave is nearly ready to begin your field should look something like this:

As the final wave begins you will get your first glimpse of the Abberation. If this enemy appears in a lane where you do not have a Strangler Vine planted be sure to get one there as soon as possible. Besides this all your Solar Power at this point should be spent replacing the Rocknuts at the end of the lanes, and replacing any Stranger Vines that have been wiped out by the invading Undead.

Survive this wave to complete the quest and unlock your final and arguably most fun plant; the Pumpkin Bomb.

Someone Setup the Pumpkin Bomb

While not the last quest, Setup the Pumpkin Bomb can easily be considered the most difficult. Invaders in this mission will spawn quickly, randomly, and in larger numbers than you have seen previously. This means you will need to have lightning fast reactions to spawning enemies and be prepared for almost anything.

To begin you should strive to have your field look much like it did in the previous quest:

Ideally you should have this design completed by the time the first Massive Wave spawns, if not then chances are high that you will fail.

During the first wave you will find yourself at the mercy of Zombies, Ghouls, and Aberrations that will spawn and attack from every lane. Use a combination of Rocknuts, Strangler Vines, and Pumpkin Bombs to defeat them. If you find the Pumpkin Bombs and Strangler Vines are on cool down don’t sit around waiting! Place Spitters in row E whenever this happens.

Plant loss is inevitable, so keep your cool and keep pressing on replacing plants as they are destroyed. Losing a full row of defenses during the first Massive Wave is to be expected, don’t assume this will result in a complete and total fail. If enemies cluster up, don’t be afraid to drop a Pumpkin Bomb to quickly and effectively take them out.

If you manage to survive to the second wave, your defenses will without a doubt be in shambles. Your first concern is to be sure you have two complete columns of Sunflowers, and focus the rest of your Solar Power on Rocknuts and Pumpkin Bombs until it’s time for the final wave.

In the second and final wave you will meet your very first Abominations, three of which will spawn almost immediately. Remember, Abominations are immune to Strangler Vines so don’t waste Solar Power on these plants. The best strategy to take out these tanks is to place Rocknuts in their paths and then use a Pumpkin Bomb when you have enough Solar Power available, placing them on squares that will do damage to as many enemies as possible. Since Abominations have so much health it will take 2 to 3 Pumpkin Bombs to take them out.

This wave is intense, so there is a good chance that a rogue Ghoul or Aberration will make it’s way past your defenses. Don’t be afraid to save some Solar Power and allow your Fertilize-o-Tron to take care of business if one remains in that row, instead stay focused on taking out the Abominations. If there is no defense left in the lane drop Strangler Vines to stop the enemy before they reach the house.

Don’t be surprised if you need to repeat this mission several times to complete it. When you do complete it, chances are it will be just barely and you should give yourself a much deserved pat on the back.You truly are a Zombie killing machine.

Lawn of the Dead

If you managed to keep your sanity in tact after the last phase know that you are in the home stretch with only one quest between you and your awesome Sunflower companion. In Lawn of the Dead you and your plant allies will be pitted against the vile Warden Stillwater. As in the last quest the enemies will come quickly, randomly, and in large numbers leaving you little time to build and even less time to plan.

Since this is the final stage (much like the rules in a scary movie trilogy) the rules that applied in the previous quests DO NOT apply here. Enemies and Allies alike no longer stick to just one lane, instead you will find your attackers prancing happily across the field as they please and your plants attacking enemies across lanes. Another change in this mission is the disappearance of the Progress Meter. This space will only be filled once Warden Stillwater makes his grand entrance and where the Progress Meter once was will be filled with his rather large health bar.

Before the Warden joins the fight you should focus on creating at least one column of Sunflowers and one column of Spitters. Make good use of Rocknuts to be able to complete these columns before it’s too late.

Your field should at a minimum look something like this by the time the Warden arrives(with some possible Rocknuts as well:

The Warden is not a stealthy fellow and will announce his arrival by yelling “Enough fooling around. It’s time for some hands-on management!”. You will also receive a warning instructing you to slay the Warden before you become overwhelmed via the text on your screen.

Now it’s crunch time. Fill column B with Sunflowers and column C with Sunflowers as quickly as you can, using Rocknuts and Strangler Vines to delay the clusters while you continue to build your defensive line. Keep in mind that this final stage will require a lot of maintenance on your part. From time to time the Warden will prove to be an even bigger pain in the ass than you had previously thought and will shout “Enough of your pesky pea-shooters. Let them shoot at this!” and then will proceed to toss Fertilizer onto your plants. After 30 seconds any plant with Fertilizer on it will wither and die. Replace these plants as soon as you have collected enough Solar Power to do so.

Each time one of your plants is destroyed by the Warden’s Fertilizer a green globe will appear on the field. Collect the globe to gain a buff which increases the drop cycle of Solar Power by 100% for 15 seconds. During this boost place a Strangler Vine and Pumpkin Bomb on large clusters of attacking enemies and repair any holes in your defense.

If the Fertilizer wasn’t enough, Warden Stillwater will also erect his own defenses in the form of floating Obelisks on row G. Plant Strangler Vines next to them to clear them quickly out of the way. For the rest of the battle you will need to rotate between placing Pumpkin Bombs to do damage to Warden Stillwater, repairing holes in your defense, and dropping Rocknuts to keep any other invading enemies at bay.

If you manage to survive long enough to take Warden Stillwater down, the Warden will yell “What? No! This lawn…was…mine…” and you may begin your post Zombie invasion celebration.

Speak to Brazie to complete the quest and claim your rewards!
