Photosensitive

Difficulty: Medium-Hard

Photosensitive is an achievement that can be unlocked in the Nintendo DS and Nintendo DSiWare versions of Plants vs. Zombies. To achieve it, the player must complete a night level without picking up any sun.Puff-shrooms are extremely mandatory to use for this achievement because they do not cost any sun.

Strategies
This achievement is not as hard as it sounds. On Level 2-1, just plant as many Puff-shrooms as you can, you can also use two Scaredy-shrooms if you play level 2-1 again, and you will easily unlock it. You can also use with the Garden Rake and Potato Mines so that you can build your Puff-shroom defense rapidly. You'll be stuck with 50 sun, which is two Potato Mines, so use them wisely. Squashes and Wall-nuts, which cost 50 sun, are not recommended for getting this achievement. Just remember to beware of the graves since you can't use Grave Buster. It is recommended that you bring along the Imitater to imitate Puff-shrooms. This way you can plant up to ten Puff-shrooms in an extremely fast time.


 * Note: Completing a fog level, even with Sea-shrooms, will not count towards this achievement. You also cannot get this in Whack a Zombie, Beghouled, or Beghouled Twist
