Hypno-shroom

The Hypno-shroom is a single-use mushroom that causes the next zombie biting it to turn around and attack other zombies. It is the ultimate passive-aggressive plant, for those who dislike all that messy killing. The Hypno-shroom has swirly eyes, suggesting that it hypnotizes. It seems to be based on various psychedelic mushrooms, which affects the thinking of the brain. It makes the zombies turn into a pink or purple color. The zombie will then begin to walk to the other side of the lawn, eating other zombies on its way.

Plants vs. Zombies
Hypno-shroom is the 13th plant received and obtained after beating level 2-5. It is useful to hypnotize the Football Zombie encountered in the later levels in Adventure Mode.

Plants vs. Zombies 2: It's About Time
Hypno-shroom makes an appearance once again as a premium plant. It is more powerful than it was during the previous game.

Plant Food upgrade
Once fed with Plant Food, it will glow and the zombie that eats it transforms into a hypnotized Gargantuar. It can't still take over Gargantuars themselves, as they will smash the Hypno-shroom.

Plants vs. Zombies
When eaten, Hypno-shrooms will make a zombie turn around and fight for you.

Usage: single use, on contact

Special: makes a zombie fight for you

Sleeps during the day

"Zombies are our friends," asserts Hypno-shroom. "They're badly misunderstood creatures who play a valuable role in our ecology. We can and should do more to bring them round to our way of thinking."

When zombies eat Hypno-shrooms, they will turn around and fight for you.

Special:  makes a zombie fight for you

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."

Usage
Place the Hypno-shroom directly in the path of a zombie, and when that zombie reaches and tries to eat the Hypno-shroom, the Zombie will face right and attack any other zombies that are behind it, using any special ability that zombie may have.

The Hypno-shroom cannot affect Catapult Zombies, Zombonis, or Gargantuars, as they simply smash it flat, while Dolphin Rider Zombies, Pole Vaulting Zombies, and Pogo Zombies that still have their dolphins, poles, or pogo sticks respectively will jump over it. Also, Balloon Zombies with their balloon will float over it while Bungee Zombies will simply take it.

Standard Levels
The Hypno-shroom is mostly useful for dealing with powerful enemies like Football Zombies and Dancing Zombies. Note that if the Dancing Zombie eats a Hypno-shroom, it earns the achievement Disco is Undead and all the Backup Dancers it summons thereafter will be hypnotized for some reason (probably because the Backup Dancers do not have a brain and just follow their leader). Be careful when placing the Hypno-shroom in front of a Dancing Zombie, or you may only end up hypnotizing a Backup Dancer, however, that is not necessary. Beware that when hypnotizing a zombie that has special abilities, the zombie will not always use their special ability. For example, Pogo Zombies, Dolphin Rider Zombies, and Pole Vaulting Zombies cannot use their pogo stick, Dolphin, or pole, respectively, to attack other zombies since they would have already lost them at the point where they could eat the Hypno-shroom. Screen Door Zombies and Newspaper Zombies cannot use their shield to protect them from other zombies, but Ladder Zombies will use their shield/ladder to protect themselves. Snorkel Zombie has no use to submerge to eat other zombies. Balloon Zombies have to land before they can eat the Hypno-shroom and thus, cannot use their balloons to fly above other zombies. Digger Zombies cannot dig again and eat other zombies from behind. However, Dancing Zombies will continue to summon hypnotized Backup Dancers and Jack-in-the-Box Zombies will explode and kill unhypnotized zombies. In later levels, it is nearly useless, due to the increasing numbers of zombies that do not eat, such as Gargantuars and Zombonis, as well as the large number of zombies later on.

Vasebreaker: Third Vase
Try to get the Dancing Zombie to eat the Hypno-shroom, or you will end up with too many Backup Dancers to deal with. The Dancing Zombie also summons hypnotized Backup Dancers as an added bonus.

Vasebreaker: Chain Reaction
The Football Zombie is probably the most important to get with the Hypno-shroom, as there are no Magnet-shrooms or Wall-nuts to defend with. Once it is taken care of, drop any remaining Hypno-shrooms on the far left, just in case any zombies make it past your Puff-shrooms and Left-facing Repeaters.

Plants vs. Zombies 2: It's About Time
Hypno-shroom is again, useful against powerful, single zombies. It should be noted that while Hypno-shroom is immensely powerful against single, high health zombies, it is also easily wasted if a weaker one consumes it. Zombies which do not eat are immune to the effects of Hypno-shroom, which effectively means zombies such as Gargantuars, Explorer Zombies with their torch, unless you freeze it before it gets to the Hypno-shroom, and Jetpack Zombies are impossible to hypnotize.

The Plant Food Ability can easily turn the tide of a lane by turning the zombie which eats it into a Gargantuar, themed based upon the time period being played. This means that the zombie will have 175 HP and deal massive damage to zombies in its path. However, as it takes a long time to smash, the hypnotized Gargantuar is vulnerable to crowds, especially Zombie Chickens.

Keep in mind that in four digit levels of Endless Zones will slowly make Hypno-shroom render it useless as hordes of zombies will immediately come after killing the first Zombie unless there are no Gargantuars and Wizard Zombies present on a certain level then it will still be of use though as those two pose a major threat especially if in tandem in Arthur's Challenge's case. Alternatively, you can boost the Hypno-shroom.

General

 * Hypno-shroom has spiral eyes that represent the sign of hypnosis.
 * Hypno-shrooms cannot hypnotize zombies that do not eat plants. such as the Wizard Zombie.
 * When a zombie is hypnotized, any damage to the zombie before it was hypnotized will still be there.
 * The Garlic, Hypno-shroom, Chili Bean and Sun Bean are the only plants that have an effect on the zombies if eats it.
 * However, the Chili Bean must be consumed fully for its effect to activate, and the Garlic can affect more zombies (21 to be exact).

Plants vs. Zombies

 * If a slowed zombie eats a Hypno-shroom, it will still move slowly at first after being hypnotized.
 * When a zombie bites a Hypno-shroom, no chewing sound can be heard unless it is asleep.
 * Any hypnotized zombie near an exploding Jack-in-the-Box Zombie will die, with the same animation as when they are killed by explosives.
 * If a hypnotized zombie encounters the same type of zombie, and neither zombie has taken damage, the hypnotized zombie usually will lose and die.
 * Hypno-shroom gets eaten after one bite unless it is asleep.
 * Zombies that are hypnotized by a Hypno-shroom will become purple.
 * There will also be a red aura for a few seconds.
 * When asleep, it can be eaten normally without hypnotizing the zombie.
 * The Balloon Zombie can only be hypnotized if its balloon is popped and it eats the Hypno-shroom.
 * Hypno-shroom is one of four plants that does not blink its eyes. The others are Pumpkin, Chomper, and Flower Pot. Even though the Chomper has no eyes, the Flower Pot always has its eyes closed and the Pumpkin has its eyes carved in. So technically, the Hypno-shroom is the only plant that cannot blink because of a swirly eye.
 * When a zombie eats a Hypno-shroom, you will hear a siren. The same sound also occurs when you give chocolate to Stinky the Snail or your plants in the Zen Garden.
 * The sound file for the Hypno-shroom's effect is named "mindcontrolled.wav".
 * If the last zombie eats a Hypno-shroom, the zombie will just disappear, but the red aura is still present.

 * In the DS version, it is very hard to tell the difference between the Hypno-shroom and the Imitater version.
 * It is unknown why the Hypno-shroom cannot hypnotize zombies while it is asleep. It is most likely because of that its eyes are closed and does not show the sign of hypnosis.
 * Every hypnotized zombie can kill every zombie who does not eat (Zomboni, Gargantuar) without taking damage. However, it is impossible that a hypnotized zombie will kill a full-health Gargantuar or Giga-gargantuar before it goes away.
 * The zombies who do not eat will not hurt the hypnotized zombie and still walk to your house.
 * A hypnotized Digger Zombie that is already going right will just continue on its path.

Plants vs. Zombies 2: It's About Time

 * Its Plant Food ability is the only way to obtain a hypnotized Gargantuars even though it merely transforms zombies into Gargantuars rather than hypnotizing actual Gargantuars.
 * The zombies that are currently not affected by the Hypno-shroom include the Barrel Roller Zombie, if it still has its barrel, Imp Cannon, the Pianist Zombie, the Mecha-Football Zombie, the Jetpack Zombie, the Disco Jetpack Zombie, Wizard Zombie, Zombie King, Zombie Bull while still having its rider, and all types of Gargantuars.
 * The Robo-Cone Zombie, the Shield Zombie, the Pharaoh Zombie with its casket, and the Disco-tron 3000 are affected by Hypno-shroom, despite the fact that they do not get affected by the Chili Bean.
 * If any zombie in the Far Future consumes a Plant Food upgraded Hypno-Shroom, it mutate into a Gargantuar Prime, but it will not shoot laser beams from its eyes.

 * According to its almanac entry, Hypno-shroom still has to convince a zombie to cluck like a chicken. This statement refers to how in many movies and TV shows, hypnosis causes the subject to cluck like a chicken.
 * Zombie Chickens do not eat it completely when they get hypnotized. This can be used as a source of amusement if Hypno-shroom has been given Plant Food.
 * Imps thrown from hypnotized Gargantuars fly backwards.

 * Hypnotized zombies can eat tombstones.
 * It takes two hits for a hypnotized Gargantuar to destroy a Pharaoh Zombie, proving that the casket and the zombie inside are separate objects.
 * Zombies hypnotized by Hypno-shroom die after leaving the lawn.
 * Before the 2.4.1 update, the zombies who ate it somehow spawned with full health when hypnotized.
 * Unlike in Plants vs. Zombies, the hypnotized zombies are tougher than normal zombies.
 * Now it blinks its eyes.
 * This is the second premium plant (with the first being Starfruit) that can be used without buying it (aside from Piñata Parties), and the first premium mushroom.
 * It is currently the only instant-use mushroom in this game.
 * Chicken Wrangler Zombies who eat the Hypno-Shroom with their chickens release hypnotized Zombie Chickens at other zombies.
 * The sound effect after zombies eat a Hypno-shroom is different from Plants vs. Zombies.

 * If there are hypnotized zombies on screen when the game is finished, collecting the reward will instantly make the hypnotized zombies disappear.
 * Hypnotized zombies actually die once they have reached the rightmost end of the lawn. This is proven by a Gargantuar because of the footsteps it makes.
