Level 4-9

Level 4-9 is the thirty-ninth Plants vs. Zombies level and the eighth Fog level. To complete this level, the player must not let the zombies into the house. When the player is finished with this level for the first time, he or she receives a note from the zombies.

Difficulty

 * There are only 4 squares visible for the player at the start of the level. It can be hard for the player to determine which lane zombies spawn on at the beginning of the level.
 * There are many different types of zombies found on this level.

Strategies

 * Suggested plants:
 * Sun-shroom
 * Puff-shroom
 * Torchwood
 * Split Pea
 * Cattail
 * Lily Pad
 * Tall-nut (if you have seven seed slots)
 * Plantern (if you have eight seed slots)
 * Plant Sun-shrooms and Puff-shrooms for easy defense at first.
 * Use the same strategy in Level 4-8, but use the Cattail instead of the Cactus to pop Balloon Zombies. Cattails are more efficient in Pool or Fog levels.  Try to plant at least 4 Cattails in this level for this level to be really easy.
 * Use Planterns if you want to see through the Fog. Just remember that seeing through the Fog is a luxury, it is not required.
