The Doom-shroom is a mushroom that creates a explosion that looks similar to an atomic bomb; appropriately enough, detonating it creates a crater, which the player cannot plant in for a short while, and destroys any plants it is planted on or that are planted on.
It is based on the Death cap.
The Doom-shroom's main power is to explode destroying all zombies in half-screen and leave a crater where it was planted.
If Plant Food is given to it, the Doom-shroom will explode dooming all screen, but leaving no crater.
Doom-shroom first meet Crazy Dave during the zombie apocalypse starting. Crazy Dave first asked him to join the plants, but he refused.
Later, Dave sent Repeater to try making a deal with Doom-shroom, which he accepted.
- Plant Food can be applied on its crater, that will disappear.
- The Doom-shroom is the only plant that leaves a crater.
- It's the stronger explosive plant overall.
