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

Standard Levels
Plant the Ice-shroom when tough zombies are trying to eat your other plants. Against Dr. Zomboss, the Ice-shroom can be used to destroy fireballs, and also to freeze him so he can be damaged for more seconds at a time.

Note: Try to not spam them in the boss fight, when he puts his head down use as much as you can, until you feel that he's going to go up.

In Survival: Endless it may be a good idea to plant an Ice-shroom before it is needed so it can be saved for later, but this may not work if there are hard-to-stop zombies that could get to it and eat it. In iPhone/iPod Touch/iPad version of the game, immobilize 20 full-sized zombies with a single Ice-shroom will earn you the 20 Below Zero achievement. The Ice-shroom can be planted anywhere and still freeze all on-screen zombies. It can also be used during Invisagoul to show you were th zombies are.

Whack a Zombie Mini-game
Use the Ice-shroom when you need a little extra time to whack a large wave of zombies. If you have enough Sun, you can take that time to drop a Grave Buster at the same time. Use this only during the later part of this level as there will be more Zombies.
