No Fungus Among Us

Strategy
This Achievement is relatively easy. It can be beaten by using Sunflowers and Peashooters/Cabbage-pults (Wall-nuts, Potato Mines, and Squash are optional but very helpful) on level 2-1. It is not very different from a Day level, so it can be beaten easily with a similar strategy. Cabbage-pults may be a better choice that Peashooters, as they can damage the Newspaper Zombies that appear directly. Just plant a row of Sunflowers in back, a few rows of Peashooters or Cabbage-pults in front of them, and use instant kills as necessary and you should be fine.

You can also play Vasebreaker in the Puzzle Mode. Just don't use use the mushrooms when you get it from the vases.


 * Note: Completing a Fog level without using mushrooms does not count towards this Achievement.
