Doom-shroom

Doom-shroom is the most powerful of all of the exploding plants, able to affect many zombies when exploding. Detonating it creates a gas cloud which you cannot plant in for a short while. Any Zombies surrounding it will not be destroyed in the explosion. It has an exactly damage radius of 1x1 squares. It will also not destroy Lily Pads or Flower Pots supporting it. If there is a Pumpkin planted around the Doom-shroom, it will also not be destroyed when the Doom-shroom detonates. It is the 16th plant you will receive and it is obtained after level 2-8.

Recharge: very slow

Strategy
This is the atomic bomb of all plants which can easily destroy huge waves of zombies. As it has a very slow recharge time, you will want to plant it when it can destroy the most zombies, or when you most need it. Bear in mind that it has a much bigger blast radius than Cherry Bombs, so it can easily take out huge waves of zombies. If you want to take out zombies while playing daytime levels, plant one before you intend to use it. In Survival Mode, the Doom-shroom can be used to destroy an entire wave of zombies, simplifying the process of defeating waves if your defenses are low. Planting one in the center row maximizes the amount of zombies it can kill.


 * Note: This is not as good a plant for daytime use, as you will need to spend 75 Sun on a Coffee Bean to wake it up. You may want to plant the Doom-shroom ahead of time, so as to save time when you need to wake it up and prevent the Zombies from eating it. Also it is a good idea to pumpkin it or else zombies can easily eat it, but it can waste a lot of Sun.

Trivia

 * The Doom-shroom has the largest area of effect of all exploding Instant Kill plants, so to maximize its destructive power you should plant them in the center row.
 * It is also the only Instant Kill that is a mushroom.
 * Strangely, despite the fact that a roof tile is a non-living object, the tile slowly "heals" and removes the crater left behind by a Doom-shroom. This also happens with water. This may be down to the fact that oil on water can very slowly dissolve, settle on the bottom or disperse.
 * The oil slick is the only Doom-Shroom result that isn't a crater.
 * The Doom-shroom is one of the plants, along with the Tangle Kelp, Spikeweed, Spikerock, Hypno-shroom and Cob Cannon, that have red eyes.Doomexplosion.PNG
 * The Tangle Kelp, Hypno-shroom and the Doom-shroom are the only Plants with full red eyes.
 * The cloud created by a Doom-shroom is very similar to a nuclear bomb explosion cloud (which ironically looks like a mushroom cloud)
 * At the top of the musroom cloud there are several repeated smoke clouds stacked on one another.
 * These are identical to the smoke clouds created when a Lawn Mower hits a Gargantuar, only coloured purple.
 * When the Doom-shroom is detonating, its mushroom cap will get bigger and shake heavily.
 * The Doom-shroom and the Gloom-shroom are the only mushrooms that have eyes on their mushroom caps.
 * If you look closely, you can see a red crack looking like lava flow or blood on the Doom-shroom.Doom-shroom123.jpg
 * In the Xbox version Mini-game, Heavy Weapon, the Doom-shroom is used as a Nuke.
 * When the Doom-shroom explodes, a lightning-like flash on the screen is seen.
 * The Doom-shroom is the only plant that can destroy other plants.
 * Sometimes, one Doom-shroom can destroy a Gargantuar that did not receive any damage.
 * The Doom-shroom is seen detonating during the Plants vs Zombies Trailer.
 * The Doom-shroom, the Gloom-shroom, the Fume-shroom, and the Ice-shroom are the only mushrooms that frown.
 * The Doom-shroom can destroy other plants (Lily Pads, Flower Pots and Pumpkins) and leave a Crater, but can't destroy a Gargantuar instantly.
 * The Doom-shroom is one of the twelve plants that appear in the seed selection screen after you get the Grave Buster on the online version, the others are: Ice-shroom, Lily Pad, Potato Mine, Threepeater, Tangle Kelp, Jalapeno, Spikeweed, Torchwood, Tall-nut, Cactus and Blover.
 * The Doom-shroom is the only exploding instant kill that can be detonated manually, though this can only happen in the Day. The Coffee Bean serves as its detonator.
 * Unlike the Jalapeno and Cherry Bomb, only the mushroom cap swells before exploding.Doom-shroom.gif
 * The Doom-shroom is the only explosive that shows no sign of exploding in the almanac. (excluding the Potato Mine's red-blinking antenna)
 * Sometimes Doom-shroom blast can reach 6x5 when condition was posible to kill all zombies
 * The Doom-shroom seams to be the only explosive plant that is in a calm pose in the Suburban Almanac entry.
 * Strangely, the crater doesn't make the zombie get pass it lower. This also happened with the daisies.
 * It is unknown why a Doom-shroom costs less than a Cherry Bomb, although it may be because it leaves a crater that can't be planted on for a few minutes.
 * Or it would cost an extra 75 sun to use during the Day.
