Destruction mushroom.

1. The Destruction Mushroom does great damage and can destroy zombies in a large area. Tactical Cucumber will cause 7200 points of damage to all zombies on the field, but will only cause 1800 points of damage to zombie robots. So the Destruction Mushroom is powerful.

2. The Destruction Mushroom was a plant often called an endless artifact in the first generation. Clicking on the Tactical Cucumber will consume 15 diamonds, then all targets on the screen will be temporarily frozen, and cucumber bombs will fall from the sky. So the Destruction Mushroom is powerful.
