| No Fungus Among Us|
Complete a Nighttime Level without planting any mushrooms.
Difficulty: Hard-very hard (Extremely easy in I, Zombie)
No Fungus Among Us is an achievement that can be obtained on the Steam, iOS, PC, PS Vita, Nook, and Android versions of Plants vs. Zombies. It is worth ten points on the Game Center. It requires the player to complete a Night level without using any mushrooms. There is a glitch on the PC and Steam versions where it can be completed in I, Zombie.
Strategy 2: Begin the level by picking the Sunflower, Cabbage-pult, Kernel-pult, Potato Mine, and Wall-nut. Now, you should pack any instant-kill plants you prefer to use. Purchase the Garden Rake as well. This should be done on Level 2-1, and the guide is assuming it is. If you followed the procedure, getting this achievement will be simple. When the level starts, plant a Sunflower in the same row as the Garden Rake. Proceed to do so once more. At this point, do nothing but plant Sunflowers until you have at least five, keeping them out of harm's way. Remember, do not plant them past the second row. Take full advantage of the Lawn Mowers and ignore zombies until you have enough Sunflowers that you can use to retaliate. Now, you may plant a Potato Mine in front of a proceeding zombie to further delay them. When you have a fair amount of Sunflowers, begin to plant Cabbage-pults and Wall-nuts to obstruct the incoming invaders. Do not waste your time using Kernel-pults yet. However, once you have every lane is guarded by a Cabbage-pult, you may now plant Kernel-pults. At this point, things will play themselves out as if it were a daytime level.
This strategy can be used when you first play Level 2-1. However, you will end up losing at least one Sunflower, as you will not have the rake or any other plants after Level 2-1. The strategy is exactly the same, replacing all catapult plants with Peashooters.

- It and Photosensitive are the only achievements that require the player to beat a Night level. However, Photosensitive requires the player to pick up absolutely no sun instead of not using mushrooms.
- Playing an I, Zombie level without mushrooms such as the first level also counts for the easiest way to get this achievement, even on Game of the Year PC.
- This is one of two achievements in Plants vs. Zombies that rhymes. The other is Flower Power.
