Doom-shroom

The Doom-shroom is the most powerful of all of the exploding plants, able to affect every row when exploding (assuming it is planted in a location allowing it to do so).

Usage
Plant it and watch it clear the screen. It has a radius of about 2.5 squares. It takes about three minutes for the crater to vanish, during which time, nothing can be planted there. The Doom-shroom will also muddy the water or crater roof tiles, destroying the Lily Pad or Flower Pot it was planted on and the Pumpkin around it.

Strategy


This is the Atomic Bomb of plants. It can easily destroy huge waves of zombies. Although a powerful plant, it still can't defeat Gargantuars in a single blow. As it has a very slow recharge time, you will want to plant it when it can destroy the most zombies. In Survival: Night and Fog, the Doomshroom can be used to destroy an entire wave of zombies, simplifying the process of attacking waves if your defenses are low.


 * Note: This is not as good of a plant for daytime use, as you will need to spend 75 Sun on a Coffee Bean to wake it up. However, it may be helpful to leave them dormant until you need them during the day.
