Similar to Plants vs. Zombies 2, planks appear in this world, but it expands one more column, so five planks can be present in each lane.
Also, a new feature not found on Plants vs. Zombies 2 is the big mast, which can make the zombies enter from the middle of the lawn similar to Swashbuckler Zombies. Zombies moving on the big mast cannot be damaged until they get off the mast.
- This is currently the only area from Plants vs. Zombies 2 to not have a majorly redesigned lawn.
