Like Day 17, there are not a lot of zombies present. While only containing Surfer Zombie and Zombie Bull as zombies from other worlds, this level should be very easy for the player. For one, no portals spawn. Second of all, the main threat the player faces is the Balloon Zombie, which appears multiple times during the course of the level but can be countered easily using Blover. However, this zombie does not appear very early, so the player has some time to defeat him. In addition, there are four Newspaper Zombies in the level. Finally, Surfer Zombies can be dealt with easily but Zombie Bulls can be a bit problematic. Place plants closer to the right to slow the Zombie Bull quicker.
The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.
