For other uses, see Hypno-shroom (disambiguation).

Hypno-shroom is a single-use mushroom that appears in both main series Plants vs. Zombies games, and in Plants vs. Zombies: Great Wall Edition. In the first game, he is unlocked on the Night levels as the twelfth plant unlocked overall, while in the second game, he is a premium plant that can be purchased with 100 gems. He is tied to Dark Ages Part 1.

Hypno-shroom converts the zombie that eats him to the player's side, causing it to turn around to attack its former comrades. The zombie retains its current health, and in some cases, special abilities when converted. Zombies that run over or smash the Hypno-shroom instead of eating it will not be affected.


Psilocybe azurescens 123020

Hypno-shroom is based on the psilocybin mushroom, a mushroom that contains the psychoactive compounds: psilocybin (which the body breaks down to psilocin), baeocystin and the alkaloid, specifically the azure psilocybin mushroom (Psilocybe azurescens) due to the cap's shape as well as possibly its shininess. He may also be based on other psilocybin mushrooms used for recreational drugs as well as entomopahogenic fungi that can control animals (typically insects). His colors and eyes are likely based on the visual effects of psilocybin mushrooms and other psychoactive drugs.

His name refers to how it hypnotizes zombies into fighting for the player, and how he is a mushroom.

Plants vs. Zombies

Hypno-shroom is the 13th plant received and obtained after beating Level 2-5. As he is a nocturnal plant, Coffee Bean will be required to wake up Hypno-shroom on Day, Pool and Roof levels.

Generally speaking, most zombies will retain their special ability when hypnotized, but will use these for the player's benefit instead: Screen Door Zombies and Ladder Zombies can use their shields to defend themselves from bites, Dancing Zombie can summon hypnotized Backup Dancers, while Jack-in-the-Box Zombie can explode and damage nearby unhypnotized enemies. The latter does not apply to ZomBotany zombies, however, as Peashooter and Gatling Pea Zombie will continue to shoot and damage plants, and Jalapeno Zombie will still destroy all plants in its row when exploding.

Hypnotizing a Dancing Zombie will give the player the Disco is Undead achievement.

Plants vs. Zombies 2

Hypno-shroom makes a return in this game as a premium plant. Due to the absence of the sleeping mechanic, Hypno-shroom can now work immediately planted in levels outside the Dark Ages, but his cost has been increased to 125 sun (the latter does not apply to the Chinese version). His recharge speed has also been increased.

Unlike in the first game, hypnotized zombies will usually not retain their special abilities, while other zombies will have their special abilities glitched. For example, Turquoise Skull Zombie will use its crystal skull to burn zombies, but the laser will head to the player's house, and all Neon Mixtape Tour special zombies will not activate their special abilities regardless of jam. The only exception to this are the abilities regarding creating additional zombies, as any hypnotized units such as Disco-tron 3000 and Chicken Wrangler Zombie/Weasel Hoarder will create hypnotized zombies to fight for the player.

Zombie Chickens and Ice Weasels will be instantly hypnotized by Hypno-shroom without consuming the plant. Hypnotizing Chicken Wranglers or Weasel Hoarders that have not released their respective animals will cause them to instantly release them. Zombie Bulls and Rodeo Legend Zombies will still throw their hypnotized Bull Rider Imp towards the player's house, but will throw the Imp even if the Imp has already been thrown before the Bull was hypnotized.

Hypno-shroom has no trouble persuading zombies to fight on behalf of the plants. But he has yet to convince one to cluck like a chicken. "One day," he says. "One day."

Plant Food effect


Hypno-shroom with Plant Food


The result of consuming a Plant Food fed Hypno-shroom

Hypno-shroom's cap glows when fed with Plant Food, and any zombie that eats him transforms into the level's respective world version of Gargantuar. In the Chinese version, a non-costumed Hypno-shroom with Plant Food will instead transform the zombie into a Buckethead Zombie, regardless of toughness.

The Gargantuar variants will retain their special abilities and characteristic: For example, Gargantuar Prime will move more slowly and smash twice per attack, Sloth Gargantuar can throw up to three Yeti Imps, and Jurassic Gargantuar has increased durability and lowered speed. Each smash itself can either reduce a Gargantuar's health to the nearest quarter (it will take up to four smashes to instantly kill a Gargantuar) or instantly kill any other enemy. Gargantuar Prime, however, cannot fire their eye lasers, while Hair Metal Gargantuar will generate glitched shockwaves that head for the player's plants and house, which doesn't damage plants. The Dinosaurs from Jurassic Marsh will also interact with zombies affected by Hypno-shroom's effect. If the Gargantuar is damaged to the point it will throw its Imp, the Gargantuar will throw it to the third column from the left no matter where it is, so in most cases it will throw it backwards.

Enchant-mint effect

When boosted by Enchant-mint, Hypno-shroom's HP will increase by 300 DPS, and when a zombie is hypnotized by an Enchant-mint boosted Hypno-shroom, the zombies HP will be restored to 125% of its original HP.

Plants vs. Zombies

While theoretically introduced as a way to abuse high-threat enemies for the player's own advantage, Hypno-shroom faces several obstacles that prevent it from actually performing the task efficiently: Firstly, most of the more dangerous enemies such as Zomboni and Gargantuar are immune to Hypno-shroom, as they can either crush or bypass plant and will not trigger Hypno-shroom's ability. This reduces Hypno-shroom's effectiveness to mostly Buckethead Zombies, Screen Door Zombies, Football Zombies, Jack-in-the-Box Zombies, Ladder Zombie and Dancing Zombies, which are in most cases not very dangerous. Secondly, the hypnotized zombie's actual performance is only average at best, and will only worsen as the game progresses and the zombie density increases.

Because of these reasons, Hypno-shroom should be best treated as a tool to eliminate select targets in earlier levels, and phased out in favor of more powerful instants such as Squash later on. Dancing Zombie and Jack-in-the-Box Zombie are prime targets for hypnotizing, as the former can summon hypnotized dancers to fight for the player, while the latter may explode and kill all adjacent unhypnotized enemies, which is simply a Cherry Bomb, essentially.


In the Vasebreaker level Third Vase, Hypno-shroom should be used immediately against Disco Zombie to prevent them from swarming the field with Backup Dancers. Hypnotized Disco Zombies can also bolster the player's defensive force with hypnotized zombies and help cleaning up the remaining vases.

In another Vasebreaker level Chain Reaction, the Football Zombie is probably the most important zombie to get with the Hypno-shroom, as there are no Magnet-shrooms or Wall-nuts to defend with.

Plants vs. Zombies 2

Hypno-shroom continues to suffer from the lack of viable targets, and the hypnotized zombie's lacking performance against their former allies. The situation has only worsened, however, as a number of enemies are now immune to Hypno-shroom, while hypnotized enemies now almost never use their special abilities. Hypno-shroom's Plant Food is also deceptive-looking - the Gargantuars take a long amount of time to smash individual zombies and cannot take much punishment in return, and thus are incredibly vulnerable to rushes of weaker enemies, in particular, Zombie Chickens and Ice Weasels since the Gargantuar is not capable of doing area damage.

Hypno-shroom benefits from the usage of Intensive Carrot, as the former is treated as defeated when used and therefore can be revived by the latter. Imitating Intensive Carrot can therefore greatly cut down the cooldown between Hypno-shroom uses, providing that the player does not plant another plant on the tiles with Hypno-shroom. This also works if Hypno-shroom is boosted via the Zen Garden since Intensive Carrot will also create a boosted Hypno-shroom upon reviving. An effective zombie to hypnotize is an enraged Newspaper Zombie or Sunday Edition Zombie, as it will most likely destroy several zombies before being destroyed itself. If there are zombies scattered around the lane, use Plant Food on Hypno-shroom and you will have a clear lane sooner or later, or if not, the number of zombies will have decreased. However, if in Pirate Seas, with Swashbuckler Zombies, using this while the zombie is past the flowers in a "Don't let the zombies trample the flowers" level, will make you fail the objective if you don't kill everything else before the hypnotized Swashbuckler Zombie tramples the flowers. Note that this glitch seems to be fixed in the 7.0 version. Also, in levels with Zombie Kings, this can easily defeat any of them since the Zombie Kings still grant zombies knight helms when they are hypnotized, effectively making him last longer and will easily eat the Zombie King, not to mention Magnet-shroom does not steal armor items from hypnotized zombies. A boosted Hypno-shroom on the third lane can easily take out a Gargantuar, provided you damage the Gargantuar to half health with an instant-kill plant. Since the Imp will always be throw to the third column, they will always end up eating the Hypno-Shroom and because he's boosted, turns into a Gargantuar, before going back and decimating the zombies in his lane. A Jalapeno or just any other area-damage plants can also help out, by destroying groups of weak zombies since Gargantuar's attacks are single-target only. A hypnotized Gargantuar Prime has an advantage as it smashes two times each time it encounters an enemy, which allows it to quickly take out the other mechanical enemies who will often resist a single smash as it smashes twice in a row. Freezing or slowing plants also help out as they prevent the zombies from attacking, giving the Gargantuar more time to kill the zombies.

Specific to Plants vs. Zombies

  • If a slowed zombie eats him, he will still move slowly at first after being hypnotized.
  • When a zombie eats him, the player will hear a siren. The same sound also occurs when the player gives chocolate to Stinky the Snail or to their plants in the Zen Garden.
  • If the last zombie of a level eats him, said zombie will instantly vanish.
  • If a hypnotized zombie encounters a regular zombie eating a plant, the other zombie will not change targets, allowing the hypnotized one to eat it without being damaged.
    • Gargantuars will ignore hypnotized zombies. That being said, it is possible for a zombie to eat a gargantuar in 15 seconds, if the player somehow prevents the gargantuar from moving.
  • Hypnotized Peashooter/Gatling Pea zombies will still shoot peas at the player's plants, while the Jalapeno zombie will burn the plants without burning the zombies.

Specific to Plants vs. Zombies 2

  • Hypnotized zombies can eat tombstones, frozen blocks, Surfer Zombie's surfboards and Octo Zombie's octopi.
    • They are no longer ignored by the gargantuar. Each gargantuar smash deals 1800 damage to them and 900 damage to other gargantuars. Additionally, if a hypnotized zombie was eating a plant, it will change it's target when a hypnotized zombie is attacking it.
  • Before the 2.4.1 update, the zombies who ate him somehow regained their full health after being hypnotized. This still happens to robot zombies like Zombie Bull.
    • However, this is still not fixed in the Chinese version.
  • He used to make zombies tougher than normal zombies when hypnotized before 2.9.1 version.
  • Hypnotized zombies are affected by the Power Toss, but they will never be tossed off the screen, similar to non-shrunken Gargantuars.
  • If a hypnotized zombie eats a Sun Bean before it was hypnotized, it will still generate sun as it battles with other zombies. It will generate whatever sun it has left a few seconds after it exits the lawn.
  • Hypnotized zombies can trample the flowers, causing the loss of a level. This is because even though they are hypnotized and therefore on the plants' side, they still count as zombies. This has been patched in 7.0.1. Also, if a hypnotized gargantuar was kicked into the player's house by a Breakdancer Zombie, it will cause the loss of a level.
  • After Zombie Chickens and Ice Weasels eat him and become hypnotized, the Hypno-shroom be kept instead of disappearing. Also, if they eat him when he's fed with Plant Food, they will not transform into Gargantuars, and instead will remain as themselves.
  • He is featured for free in Dark Ages - Nights 4 and 8.
  • He is the first plant to have a positive view on zombies, with the second being Blooming Heart.
    • Coincidentally, both are premium plants.
  • Turquoise Skull Zombie can instantly kill hypnotized zombies and hypnotized Gargantuars with its crystal skull. A hypnotized one will still burn the player's plants.
  • Hypnotized Troglobites will still push ice blocks backwards towards the player's house.
  • If a poisoned zombie is hypnotized, it will be cured from the poison.
  • In the Transformation Bundle in the store, he is mistakenly referred to as "Hypnoshroom."
  • On March 16, 2017, he became one of 4 premium plants to be permanently purchasable with 100 gems, along with Squash, Jalapeno and Pea-nut.

Specific to the Chinese version (China only)

  • He will not be spawned by Spore-shroom (level 2 and above), despite also being a mushroom.
    • This is ironic as he appears on Spore-shroom's level 3 upgrade icon.
