This level is a tutorial about how the Magnifying Grass works. It works by having at least 50 sun to use, and the Magnifying Grass will use 50 sun in a projectile that deals decent damage, enough to defeat a Buckethead Zombie in 3 uses. The player is given two sun producers in this level, most likely to maximize Magnifying Grass' effectiveness. A big factor in this level is that Magnifying Grass is the only plant that can attack. Another big factor is the absence of Blover, while there are many Bot Swarms and Jetpack Zombies. There are also Robo-Cone Zombies, which will be hard to deal with, even with E.M.Peach given. The plants and Power Tiles in this level lead to many strategies to which plants should be given Plant Food. For example, using some Twin Sunflowers as well as an Iceberg Lettuce.
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.
Plant three Magnifying Grasses on yellow tiles and two Magnifying Grasses on green tiles. Tap one Magnifying Grass to spend sun for killing the zombie ahead of it.
Plant one Infi-nut on each lane to protect your plants if you have trouble. Now, plant more Sunflowers and Twin Sunflowers. This will not only make more sun, but it will also make the Magnifying Grasses' Plant Food upgrade more effective.
