As with many levels with a limited selection of plants, this one can also be difficult and hard-to-manage if the player does not react quickly to the dangers.
Stallia is vital, but it can be unreliable due to its arrival rate on the conveyor belt. Either way, the player should prioritize the zombie groups closest to home.
The biggest threat in this level are the Bug Zombies, as neither A.K.E.E. or Red Stinger can kill the bug before it carries the zombie deep in the lawn. This is even more dangerous when they are the single plants in their lanes. To avoid the loss of lawn mowers, the player should allow themselves to use Stallia on Bug Zombies even if there are other zombies that could otherwise need it more.
The secondary threat is Buckethead Adventurer Zombie. It will absorb damage dealt by Red Stinger, and the small amount of A.K.E.E.'s given will not deal a lot of damage either. In dire situations, Plant Food should be used, preferably on A.K.E.E. Red Stinger's is a better option when the entire lane has accumulated zombies, particularly Bug Zombies.
While the player will encounter Stallia for the first time in this level, its Plant Food is not particularly useful. It should only be considered if three or more lanes are in danger.
Try to use Stallia's 3×3 range of slowing to slow down Bug Zombies that are coming into the player's defenses.
