A crater is a circular one-tile hole environment modifier on the player's lawn resulting from the explosion from Doom-shroom or having a plant eaten in the mini-games Beghouled and Beghouled Twist in Plants vs. Zombies. It fades away after three minutes in most levels, and the appearance changes after every 90 seconds; but in Beghouled and Beghouled Twist the only way to get rid of it is to use the "Refill Crater" ability, which costs 200 sun (which is only possible in those mini-games and cannot be used in regular levels). The player cannot plant anything on a crater, unless they are playing Beghouled or Beghouled Twist, and must wait for it to disappear. It works like any other space does to zombies, so some consideration must be taken on when to use Doom-shrooms.
Types of craters
Normal craters appear on the grass, in the day and the night. If a Doom-shroom is planted in the pool (with a Coffee Bean to wake it up if it is daytime), the crater will look like a small oil spill with a large debris in the middle (probably from the destroyed Lily Pad) on the water's surface. If one is planted in a Flower Pot on the roof, the crater takes the form of a small hole on the roof tile.
- Zombies can still go over the crater and the large crack on the roof while aquatic zombies pass through the oil slick and debris.
- It is odd that when the zombies walk on a crater (on the roof or on the ground), they do not go a little lower than normal again, and instead they go straight above the crater like a normal space and appear to be hovering.
- Unlike a crater in actual life, the crater in Plants vs. Zombies appears to be very small.
- Lava tiles made by Lava Guava act similarly to craters in the sense that the player cannot plant anything on them. The difference is that lava tiles damage zombies.
- It is unknown exactly how the crater is able to refill on the Roof.
- There are no graphics for a crater on the Night Roof, since the player is not supposed to use Doom-shroom on the only level it appears in Level 5-10.
- It is unknown what happens if the player hacks Doom-shroom into appearing on a Night Roof stage.
