In this level, the player is introduced to the Pogo Zombie, which is capable of easily jumping over their plants, except Tall-nuts. This zombie also uses fog as its advantage to get through the player's defenses faster, so clearing the fog out is one of the first thing the player should do.
Plant Sun-shrooms and Puff-shrooms for an easy defense at first.
Try to plant as many Split Peas evenly on every lane for maximum damage to Pogo Zombies. When the Pogo Zombie jumps over a Split Pea, the Split Pea will deal double damage to it, killing it faster. To double the damage, plant Torchwoods behind and in front of the Split Peas.
