Level 4-12 was a bonus level, and the twelfth Fog level in Plants vs. Zombies: Journey to the West. The player had to pay 20 gems to gain access to this level. To complete the level, the player had to not let the zombies cross the yellow line.
The Pogo Zombie was capable of easily jumping over their plants, except Tall-nuts. This zombie also used fog as its advantage to get through the player's defenses faster, so clearing the fog out was one of the first thing the players should have done.
This zombie would also have made it hard for the player to complete the objective, so try to move the Hero Plant to the lane it appears to deal more damage.
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.
