Plants vs. Zombies: Game of the Year – 100% Achievement Guide (How to Unlock All)

My own “100% achievements guide” for Plants vs. Zombies based on my own experiences.

Understanding This Guide

All credit goes to Bluey!

For this guide, most achievements are based on the assumption that you have already completed Adventure Mode once. For example:

• For the “Don’t Pea in the Pool” achievement, I say to “complete a pool level using only catapult-plants (cabbage, kernel, and melon).” Obviously, you don’t get these plants until the roof levels, which are after the pool levels.
• For the “Good Morning” achievement, I say to “use puff-shrooms and coffee beans in order to complete this achievement.” Obviously, you don’t get any mushroom plants or the coffee bean until later on.

I believed that going through Adventure Mode twice would be the easiest to do these achievements as you need to go through it again to find the Yeti zombie.

I got all of the achievements in roughly 62 hours; however, that does not mean you can do it faster or slower.

SPUDOW!

• Difficulty Rating: 1/5
• Blow up a zombie using a potato mine.

Any zombie that comes into contact with a charged potato mine will be killed. You get the plant very early in the game, so it’s very easy for this to be your first achievement. However, note that potato mines have a resting period after they are planted before they are ready to blow a zombie(s) up!

Explodonator

• Difficulty Rating: 1/5
• Blow up 10 zombies with a single cherry bomb.

While this is relatively hard to happen in early levels, this achievement can easily be done during a wave of zombies in a later level in Adventure Mode!

Or, you can do this in survival mode, where there is a lot of zombies at once.

Penny Pincher

• Difficulty Rating: 1/5
• Pick up 30 coins in a row on a single level without letting any disappear.

This achievement is straight forward and very easy to do – you just simply have to keep clicking on the coins. It is unlikely you will miss any coins since it takes a while for them to disappear.

Disco is Undead

• Difficulty Rating: 1/5
• Hypnotize the lead dancer zombie.

All you need to do is plant a hypno-shroom in front of a dancing zombie. The dancing zombie will eventually attempt to eat the hypno-shroom, which will then hypnotize it.

Home Lawn Security

• Difficulty Rating: 3/5
• Complete adventure mode.

Straight forward – just complete adventure mode!

Roll Some Heads

• Difficulty Rating: 1/5
• Bowl over 5 zombies with a single Wall-Nut.

This achievement is very easy with dancing zombies that allow you to get three easy hits (with a single Wall-Nut). Then, if there are zombies behind it, you are likely to hit five total zombies, getting this achievement.

This achievement is arguably luck-based; but, it is likely that you will get it after completing either of the minigames for Wal-Nut Bowling (usually the second one is easier, but this can be done with the first Wal-Nut Bowling minigame).

Don’t Pea in the Pool

• Difficulty Rating: 1/5
• Complete a daytime pool level without using pea shooters of any kind.

Complete a pool level using only catapult-plants (cabbage, kernel, and melon).

Morticulturalist

• Difficulty Rating: 3/5
• Collect all 49 plants.

You must get all plants from Adventure Mode AND buy any plants in Crazy Dave’s shop. This includes all “pink plants” as well as the Imitater.

Usually, after completing the game (with a Gold Sunflower Trophy), you will have generated enough money to buy all plants (and a lot more). Thus, one can just play the game normally and you will eventually have enough money to get this achievement.

Ask Me About Mustache Mode

• Difficulty Rating: 1/5
• Enable Mustache Mode.

You have to type “mustache” or “moustache” while playing a game or when you’re on the main menu. This will make some types of zombies have mustaches.

Beyond the Grave

• Difficulty Rating: 4/5
• Beat all 20 mini games.

You have to beat all of the 20 mini games in the game. Generally, they are straight forward and easy to complete, while others may require more time. Use resources like YouTube and google to figure out how to complete a specific mini game.

Sunny Days

• Difficulty Rating: 3/5
• Get 8000 sun during a single level.

Overall, this achievement is very easy to complete but it may take a few tries (and it’s time-consuming). Go onto Survival: Day (Hard) and then plant two rows of sunflowers. If possible, upgrade these sunflowers into twin sunflowers. Plant as you normally do, but you will get a surplus amount of sun that will eventually turn into over 8000 sun.

While a player may be able to complete this in Survival: Day, you may run out of time. A player may be able to do this in Survival: Pool (Hard) or Survival: Pool, but I found Survival: Day (Hard) to be the easiest to complete this achievement. I also found this to be the most “natural” way to complete this – you don’t have to purposely postpone a level to get more sun and then wait a while to collect sun.

Playing the mini game “Zombiequarium” is also a common way to get this achievement.

Nobel Peas Prize

• Difficulty Rating: 4/5
• Get the golden sunflower trophy.

You have to complete Adventure Mode, all mini games, all puzzles, and all survivals (excluding Endless versions of specific games).

Individual games may be difficult – if you are stuck on a certain level, look up a guide on YouTube or Google.

Overall, this achievement is not difficult, but it’s quite time-consuming. After you are finished the mini games, you simply just grind out the puzzles and survivals – they aren’t that difficult.

Cryptozombologist

• Difficulty Rating: 2/5
• Discover the top secret zombie.

You have to replay Adventure Mode after completing it once and then get to level 4-10 to find the Yeti (the top secret zombie).

No Fungus Among Us

• Difficulty Rating: 2/5
• Complete a nighttime level without planting any Mushrooms.

Quite simple – just use sunflowers and pea shooters! To start off a nighttime level, use potato mines to fight off the first few zombies. Then, after the first few zombies are killed, you should have enough sun to start planting some pea shooters. Continue to use pea shooters and potato mines to complete the level. Do not be afraid to use some lawn mowers to complete this.

I would recommend doing this on level 2-1 of Adventure Mode.

Grounded

• Difficulty Rating: 2/5
• Defeat a normal roof level without using any catapult plants.

This is slightly difficult to do. Here are some common strategies…

• Use pea shooters near the right side of the roof (where there isn’t a slope). Defend the plants with Wall-Nuts and Tall-Nuts.
• Use Gloom-shrooms and garlics to lead the zombies between two rows of Gloom-shrooms. While this one does work with easier roof levels, you may not get enough sun in time to do this method.
• Farm sun and plant only Chompers. With enough sun, you can have multiple rows of Chompers.

Popcorn Party

• Difficulty Rating: 3/5
• Defeat 2 Gargantuars with Corn Cob missiles in a single level.

This is fairly simple to do. You can usually complete this in Survival: Endless as, in later levels, there will be a lot of gargantuars.

Corn Cob missiles deal an amount of damage equivalent to one Cherry Bomb, one Jalapeno, or one Squash. Thus, it may be useful to have two corn cobs ready to use on a gargantuar(s).

Immortal

• Difficulty Rating: 4/5
• Get to 20 flags in Survival Endless.

This achievement is slightly difficult to do and it takes a while. Make sure to grind up sun early on and have a lot of defense for all sorts of zombies.

• Magnet-shrooms for metal zombies.
• Cattail for balloon zombies.
• Spikerock for vehicle zombies.
• Tall-nuts and pumpkins for defense.
• Twin sunflowers for sun.

Towering Wisdom

• Difficulty Rating: 3/5
• Grow the Tree of Wisdom to 100 feet.

Since each food packet is 2,500 and grows one foot of the tree, it will cost 250,000 to grow the tree to 100 feet. This may take a lot of money grinding in order to get, or, you can use the infinite money glitch (search it up on YouTube or Google).

Good Morning

• Difficulty Rating: 2/5
• Complete a daytime level by planting only Mushrooms and Coffee Beans.

This is very simple to do – especially on Level 1-1 and/or Level 1-2 of Adventure Mode where there are only regular zombies to defeat.

Use puff-shrooms and coffee beans in order to complete this achievement.

China Shop

• Difficulty Rating: 4/5
• Get to a streak of 15 in Vasebreaker Endless.

The key to this is patience. Start with the vases on the right side and work your way towards the left. Use squashs to defeat high-defense zombies. Do not try and break too many vases at a time – that will lead to you losing!

Better Off Dead

• Difficulty Rating: 5/5
• Get to a streak of 10 in I, Zombie Endless.

This is, by far, the hardest achievement to get. A combination of luck and skill is needed to get this achievement.

• If you want to get this achievement I would recommend at least 1,000 sun at the end of level one, and 2,000 sun at the end of level two. If you fail to get over 2,000 sun at the end of level two, I would recommend restarting.
• Memorize how many hits each zombie can take. For example, it is critical to remember that an imp zombie can go over a spikeweed as it takes only two of the three needed hits to kill it.
• Take out magnet-shrooms as quickly as possible.
• Use a dancing zombie on a non-threatening lane (not on the first or last lane as you want the dancing zombie to spawn zombies above and below it) to take out three lanes.
• Sometimes, it can be fine to just a buckethead zombie to take out a row. However, you can also use a digger zombie to take out an entire row and then use an imp zombie to go and eat the brain. This should only be done if there are no plants that can attack it from other lanes (such as a threepeater or starfruit) and there are no split peas.
