This level introduces Shadow-shroom to the player. When eaten, it poisons the zombie that ate it over time. Using Moonflower in conjunction with Shadow-shroom can help wipe out huge hoards, as the poisoned zombie can pass the poison effect onto another zombie (if Shadow-shroom was powered up). In addition, it also hints to the player that Shadow-shroom negates armor, shown by making Newspaper Zombie eat it. Unlike most levels in this world, this level allows for plenty of time to get defenses going, only making this level easier. Overall, this level should not be too difficult for the player, as the special zombies are easy to deal with, but should be killed quickly, as they can cause some ruckus deep in the lawn. Using Garlic is not mandatory, but it can lead for some unique strategies for this level.
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.
