Ice-shroom frowns, not because he's unhappy or because he disapproves, but because of a childhood injury that left his facial nerves paralyzed.

Ice-shroom is a mushroom appearing in Plants vs. Zombies. When activated either through normal planting in Night and Fog levels, or through waking up via Coffee Bean in levels with daylight, Ice-shroom will freeze all zombies currently on the field for 3.25 seconds, dealing 20 damage Afterwards, the affected targets will continue to be chilled for another 16 seconds, during which their movement and attack speed are halved.

Airborne enemies will only suffer from the chilling and damaging effect while Zomboni, Zombie Bobsled Team, and underground Digger Zombie are immune to Ice-shroom altogether. Fire-based attacks can also remove them.

Origins

The "ice" in his name refers to the fact that he freezes zombies with ice and the "shroom" in his name refers to the fact that he is a mushroom.

Judging by his color and flat cap, Ice-shroom might be based on the blue green aniseed toadstool (Clitocybe odora), a blue-green mushroom that grows near deciduous and coniferous trees.

Strategies

Ice-shroom is a useful plant that can help the user in delaying the horde and maximizing the plants' efficiency. As he can affect every single enemy on the screen, Ice-shroom will prove to be highly useful in normal levels, as other slowing options are either expensive or limited in scale. Ice-shroom's value, however, suffers greatly in Survival: Endless, as the player is likely going to have enough Winter Melons to suppress the horde, and the stunning duration of only 3.25 seconds is too trivial to have a great impact on the battle.

Unlike most other mushrooms, the nocturnal plant mechanic does not necessarily affect Ice-shroom negatively, as he will not activate immediately when planted in daylight levels. This allows the player to "stockpile" Ice-shrooms by planting them on safe space and activating them when needed. Pumpkins can also be used to guard sleeping Ice-shrooms, giving the player more liberty in storing them for further use.

Surprise attacks

For Pool and Fog levels, Ice-shroom could be activated in 3 seconds before the disappearance of "a huge wave of zombies is approaching" to prevent zombies rising from the water. This strategy is very important in the Survival: Endless if your unprotected plants are set in the rightmost 8 tiles of the pool. On the Roof, Ice-shroom could also be activated when the bungee zombies begin to drop ambush zombies at the final flag to stun and freeze them. The ambush zombies can be stunned and frozen in midair as well. Giving time for the plants to deal with the zombies.

Level 5-10 and Dr. Zomboss's Revenge

Ice-shroom is provided at this level as the only method to negate Dr. Zomboss's fireball attack. Therefore, the player should not try to deplete their stock too quickly, and instead, only use Ice-shroom when either a fireball or dangerous enemies are present. Stunning Dr. Zomboss when he lowers his robot can also speed up the level by giving the plants more time to damage him. However, unless there is an iceball present, avoid using Jalapeno when he is frozen, as the fire will take away both the chilling and freezing effect.

Invisi-ghoul

As invisible zombies will still have ice formed on their feet when frozen, Ice-shroom can be used to scan the lawn for potential threats. Do note though that this will not work on pool lanes.

Survival: Endless

In Survival: Endless, Ice-shroom is vital for suppressing Jack-in-the-Box Zombies, alleviating pressure, maintaining tempo, and stopping surprise attacks. Stockpiling Ice-shrooms remains a powerful strategy, and there are three ways the player could do this:

• Placing Ice-shroom on the pool row is the safest option since there is much less pressure from the zombies in these lanes. However, the pool is also the best place for installing Cob Cannon and Twin Sunflower for the same reason, therefore, this option will force the player to sacrifice great amounts of firepower.
• Placing Ice-shroom on the back columns in normal lanes will expose it to Imps and Digger Zombies, forcing the player to divert further attention to Pumpkin maintenance. This is usually the preferred option, however, since it does not require much firepower sacrifice.
• Placing Ice-shroom at the frontline is the most dangerous option, as this will put Ice-shroom in the path of various threats such as Zombonis, Football Zombies, and Gargantuars. This is usually a last-ditch option, but it still has its merits, namely not allowing Imps to attack Ice-shroom and not requiring Pumpkin if the crowd is well controlled. This can be used at the beginning or the end of a level, when Zombies are far away. Squash can be used to temporarily protect Ice-shroom.

Trivia

• When he explodes, snowflakes can be seen.
• He is one of the twelve plants who were seen in the seed selection in the web version after obtaining the Grave Buster, the others are Doom-shroom, Potato Mine, Lily Pad, Threepeater, Tangle Kelp, Jalapeno, Spikeweed, Torchwood, Tall-nut, Cactus, and Blover.
• He is the only explosive plant in Plants vs. Zombies that is not an instant kill.
  • He is also the only explosive plant in Plants vs. Zombies that only deals one normal damage shot.
• He and Blover are the only instant-use plants that affect the entire screen.
  • Thyme Warp and Ice Bloom also have this trait, but they only appear in Plants vs. Zombies 2.
  • In Column Like You See 'Em, Jalapeno in a whole column of empty Flower Pots also affects the entire screen.
• When used on a Pool or Fog level, the pool's animation stops until the zombies are unfrozen.
• Even though his Suburban Almanac entry claims he does very light damage, it is equivalent to a pea, whose damage is described as "normal".
• If the Ice-shroom is crushed by Zomboni or Catapult Zombie before his explosion, it still occurs per normal.
  • The same can also happen if an Ice-shroom is placed on a Flower Pot and the pot is crushed.
  • However, this does not applies when it sleeps as if they are crushed by Zomboni or Catapult Zombie, its flattened sprite will instead show and despawns after 5 seconds. When an Ice-shroom is asleep on a Flower Pot and the two aforementioned zombies and Gargantuar crushes them, the Ice-shroom alongside with the Flower Pot will be crushed.
• With proper timing, you can use him to freeze the zombies right before the final wave and preventing ambushing zombies to be spawned.
• He and Gold Magnet are the only plants in Plants vs. Zombies with a very slow recharge that cost less than 100 sun.
