Level 4-11 is a bonus level and also the eleventh Fog level in Plants vs. Zombies: Journey to the West. The player must pay 20 gems to gain access to this level. To complete the level, the player must not spend more than 2000 sun.
This level will be difficult to beat without any instant-kills or Split Peas, as there are Digger Zombies that can walk from the left side of the lawn.
There will also be a lot of Jack-in-the-Box Zombies, so the player must have a lot of attacking plants when they come so they can defeat them before they explode.
The objective can also cause problems for the player, as the Jack-in-the-box Zombies can wreck of the player's defenses easily if the player is careless.
