Level 4-1

Level 4-1 is the thirty-first Plants vs. Zombies level and the first Fog level. To complete this level, the player must not let the zombies into his or her house. When the player is finished with this level for the first time, he or she earns the Plantern.

Difficulty

 * The fog covers three squares on this level, leaving 3.5 squares visible for the player.
 * The Jack-in-the-box Zombie may explode and take away some precious plants.

Strategies

 * Suggested plants:
 * Puff-shroom
 * Sun-shroom
 * Sea-shroom
 * Peashooter
 * Wall-nut
 * Squash
 * Lily Pad
 * Tangle Kelp (if you have eight slots)
 * Don't worry about the fog too much...yet. Worry about it in later levels.  Start out with planting Sun-shrooms and Puff-shrooms on the left side of the lawn, with the occasional Sea-shrooms when it recharges.
 * When you have enough sun, plant the Peashooters as far on the left without digging up Sun-shrooms (digging up Puff-shrooms are okay because they are free).
 * Use instant kills when zombies get too close to your house.
