Nebulaphile

Difficulty: Hard-Very Hard

Nebulaphile is an achievement unlockable on the DS version of Plants vs. Zombies. In order to complete it you must complete a very foggy level without using Blover, Plantern, or Torchwood. The extremely foggy levels required for this achievement are the levels from 4-7 to 4-9. It is extremely similar to the achievement Blind Faith. The only difference is that Torchwood are not allowed.

Strategies
To get it, you should pick the following: Scaredy-shrooms play the most important role. They are cheap and let you know if there are any zombies in a lane. As the achievement states, you can't use the fog removers. Gloom-shrooms are cheaper than Threepeaters, so they should be used. A good strategy is to plant Garlic with Tall-nuts and Gloom-shrooms behind them on the second and fifth rows.
 * Sun-shroom
 * Puff-shroom
 * Scaredy-shroom
 * Wall-nut
 * Gloom-shroom (with Fume-shroom, of course)
 * Garlic
 * Tall-nut

Trivia

 * "Nebulaphile", although not a real word, is related to the word "nebulaphobia" which is fear of fog.
 * The Suffix "Phile" means to love or like something, so the Nebulaphile Achievement means the opposite of Nebulaphobia.
