This will include some very rare, rare, harmful, funny, weird, strange, or useful glitches that may occasionally occur in Plants vs. Zombies.
Pole Vaulting Zombie glitch
If a Pole Vaulting Zombie jumps over a plant with a Tall-nut behind it, it will crash into the Tall-nut and start eating it, despite the Tall-nut being behind the zombie. This occurs mostly when there is a ladder on the Tall-nut, the Pole Vaulting Zombie will climb over the ladder, try to jump over the next plant, but crash into the Tall-nut and have to go over the ladder again.
Wrong Value glitch
Sometimes, If someone plays a game with sell plant feature, (e.g. Last Stand) you may notice something different. The value of the sold plant will be different. For example: When you got a Melon-pult which costs 300, and you placed a Winter-melon that costs 200 on the Melon-pult, but the value of the sold plant is wrong. So for example, You got 300 sun. Then you sell a Winter Melon. The value of the sold plant should be 500. But when you try, it will result to be 700. The value that should be added in a percentage would be 800. The fact is, the Melon-pult will be replaced with the value of Winter-melon, which should result in a waste of sun in Last Stand. When placed again. It would give 200 now.
Floating Plant glitch
This rarely happens, but this is how it works: If the Jalapeno Zombie is in the pool, and he explodes, he will only remove any Lily Pads or other aquatic plants; however, he will not destroy any plants that were planted on top of the Lily Pads.
Suicide Squash Zombies glitch
First, wait when a Squash Zombie is about the middle of a square. Second, put a plant (any plant) right in front of him; His head will jump, but it will miss the plant, committing suicide. This can be useful so you don't lose any plants.
No hunger or not as often hunger glitch
Ladder Zombie's arm glitch
Ladder Zombie's arm should fall off, but does not. He still shows the bone, and the arm.
Dolphin Rider Zombie glitch
Floating ladder glitch
Grave Buster Sound Effect Glitch
If one were to pause the game at any point with a Grave Buster on screen, the chomping sound effect will restart.
Why am I still even shooting at my friends!?
If you just hypnotize any type of Peashooter Zombie (via the Hypno-shroom), then they'll just still shoot at your plants even though they are your (temporary) ally (They still attack the unhypnotized ZomBotany Zombies though.)
This bug also applies to Jalapeno Zombies, but they also kill unhypnotized ZomBotany zombies.
I've lost all my data!
If one shuts down the computer when the game is still open, the game will remove your data and the player must start all over again. If one's progress is at Adventure Mode in Day or Night, there will be dirt instead of grass on two lanes and plants will stay if the player planted it before they got it. The only way to get rid of this is to restart, but if the player has tried and it did not work, he or she must delete and then restore the data. Therefore, closing before shutting down is strongly recommended, but this does not save you if your computer hangs or crashes and forces you to reset.
Split Pea glitch
The Level Unbeatable
If one plants Grave Busters before any zombies come out on the final wave in Whack a Zombie, no money bag appears and the player cannot complete the level. This glitch makes it impossible to win the mini-game without restarting.
"Infinite trophies" glitch
If one completes a mini-game, saves process, exits, then re-enters the level, the trophy will show up again and again, without changing its value of $1000. It is useful for fast money farming.
Also, exiting a mini-game without completing it and starting a new game will let you continue from where you left off, even though that save is from a different file. (only tested with Slot machine)
Delayed laugh glitch
If one clicks "Adventure Mode" on the menu screen and holds down the mouse button, the music will play but the laugh will not and the game will not start until one let's go.
My box didn't explode
Sometimes, a Jack-in-the-Box Zombie will explode, but the animation will not be shown.
Don't you think that's a bit overkill?
There is a very rare glitch on Level 5-9 where many Gargantuars can spawn at once before the final wave instead of a single one.
Double plant glitch
If one collects a gift box and then immediately ends the level by collecting a seed packet, letter, trophy or money bag, the level end routine will also collect the box, giving the player two identical Zen Garden plants. This means the plant given to the player is decided before it is picked up. This has not been tested on other versions so far.
I left my dirt floating
This glitch happens when an ambush zombie in the pool die, there is a clump of dirt floating before disappearing.
When a Tangle Kelp pulls a frozen zombie underwater, the zombie doesn't move down with it; instead, it stays in place, then simply disappears.
Invisible Sun-shroom glitch
First, plant a Sun-shroom. Then click home (maybe wait a while) and go back in. It should have that Newspaper Zombie pause screen and rarely, it may not have the Sun-shroom on the screen, but the player still sees its shadow and it still produces sun. The shadow also grows bigger when it produces normal sun.
Whack a Zombie in Level 2-4
Occasionally, if you finish Level 2-4 in the iPad version, when you get the item then go back to the Main Menu, then go back, it will be Whack a Zombie with the plants the player had, thus making it extremely easy.
Free Puzzle game packs
Purchasing a Puzzle game pack in the Puzzle menu and switching to a different tab before the new levels appear will cause the game pack of the selected tab to temporarily unlock. For example, purchasing the I, Zombie game pack and switching to the Last Stand tab will cause the Last Stand game pack to unlock temporarily. The pack will re-lock when the player leaves the tab, or when one of the levels is played.
Invisible Zombie Glitch
Occasionally, on Level 2-4, if one exits out, waits a bit, and then goes back in, a zombie will be invisible (similar to a zombie in Invisi-ghoul).
If one pauses the game (or the game pauses itself to show zombies for the next wave on a Survival or Last Stand mode) there is a chance he or she will see both open and blinking eyes on a Peashooter, Repeater or Sunflower.
There are two variants of the glitch:
- When the game is loading, instead of saying "LOADING...." it says "MISSING..." and it will not load.
- When playing on any version of iOS on or after iOS 9, almost all text in the game says missing. This also causes lag in the game. This does not happen in Plants vs. Zombies FREE, and was the reason why the paid iOS and Android version was removed from their respective stores on August 18th, 2017 due to issues on iOS 11.
- Sometimes on Wall-nut Bowling on iPod, Football Zombies will appear. They take four hits and move faster.
- Spikerocks sometimes are shown with no large spikes after being damaged.
- Giga-gargantuars in Last Stand Endless will appear the same as regular Gargantuars, with no red eyes.
- Rarely, the iPhone can freeze if you press the pause button, requiring a hard reboot.
- The Zen Garden never supports multi-touch.
- The Dancing Zombie and Backup Dancer's graphics are very buggy.
- When the Dancing Zombie loses his arm, the entire arm disappears, including the top part. He also leaves no rip or tear in the shirt, as if he did not even have an arm hole.
- When the Backup Dancer loses its arm, there is no bone showing.
- The graphics in the Zen Garden were very buggy.
- The Watering Can switches colors after being given to a plant (e.g. green becomes golden, golden becomes green). The color change does not affect its range, so the Golden Watering Can still waters up to four plants.
- The fertilizer bag immediately disappears after the bag is opened, so the powder appears out of nowhere.
- The Bug Spray has the fertilizer animation playing behind it.
- Stinky the Snail's animations are completely messed up. His body is arranged strangely, and he has an accurately arranged duplicate next to him.
- The phonograph also has messed up graphics.
- The chocolate sometimes says x-1.
- However, all of these bugs were fixed the in 1.9.10 update.
- The game loads slower in the latest update.
- The petals on a Marigold Sprout are replaced with Stinky's eyes and regular Sprouts are shorter.
- In the latest update, when leaving a level the game says it will be "saved"; however, it will not when one returns to the level. It will instead just restart from the beginning. This will "prevent" the player from playing any Endless levels; unless they want to keep playing it for an extended amount of time until they get tired, bored, or lose.
- The game will crash while playing Portal Combat once the first portal is relocating.
- Playing Beghouled and checking the Suburban Almanac will change the sun costs shown on the seed packets to the Beghouled sun costs.
Digger Zombie glitch
In Three Hit Wonder, make the Digger Zombie lose his pickaxe on a row with a Potato Mine. When he gets to the Potato Mine, he will start eating it, despite it being armed. It will never be eaten, and other Digger Zombies that lose their pickaxe will start eating it, though other zombies will set it off (as well as a Digger Zombie with his pickaxe).
Lost arm glitch
When a zombie gets killed by the Garden Rake, his left arm will disappear without falling off.
Progress bar flag glitch
On Last Stand and any Survival level, when a new level is started, the flag(s) raised during the first wave will not go back down.
Bungee Zombies glitch
A very rare glitch during Zombie Trap may occur where every row will have 3-4 Bungee Zombies. This can allow the player to catch 24 zombies at a time.
Squished Seeds glitch
Sometimes, if the player finishes a level while a plant is squished, it may cause most of the seed packets on the seed selection for the next level to appear glitched, with the only portraits being extremely compressed plants hanging out of the packet. Although it can be hard to see what the player is picking, this glitch can also be helpful, as if it happens before a Fog level, the Fog will be reduced to small lines, making it extremely easy to see what's coming. The glitch fixes itself when the player exits the level or views the almanac.
Imitater can imitate every plant in the game glitch
In the seed selection screen, if one taps on the Imitater, scrolls down, holds, and taps fast on the bottom of the Imitater seed selection tray, he or she can imitate upgrade plants such as the Cattail without hacking and even the Explode-o-nut and Giant Wall-nut. Other strange-and-weird plants have also been reported, such as a backward Repeater, a simple plant sprout, a plant shadow, and even an invisible plant that causes the game to crash. This is a strange and very useful glitch. Also imitated upgrade plants' cost will not increase in Survival: Endless. This glitch can be repeated in some older versions of Plants vs. Zombies on the IOS.
Last Stand Glitch
When one plays Last Stand: Day, do the first flag. When it almost shows the zombies, tap the Repeater seed packet but don't place it. When the screen stops the animations of the plants, place the Repeater anywhere. Now the Repeater was placed with a random animation!
Almanac Menu Overwrite Glitch (patched)
If one were to open the Almanac and use the phone's back button instead of the game's back button, the menu music will be overwritten with the Almanac music.
Floating Cone/Bucket Glitch
As of the update that patched Almanac Menu Overwrite Glitch, if one were to leave a stage when a Conehead Zombie's cone or Buckethead Zombie's bucket has already fallen off, the cone/bucket will not disappear, but when the zombie dies, the cone/bucket will be on top of where the zombie's head would be. The method to trigger this glitch also causes Incorrect Eating Animation, where the zombie is eating but it looks like it's walking, Stuck Snorkel Zombie, where a Snorkel Zombie is frozen in place, and Vanishing Zombie, where a zombie that has already been killed appears to still be living for a few seconds.
