You must have at least eight slots of seed before starting. Choose the following plants: Repeaters, Gatling Peas, Tall Nuts, Tangle Kelps, Lily Pads, Torchwoods, Coffee Beans, and Magnet-Shrooms, After you pick them up, set up the following layout. Put two Repeaters from the back columns on every row (except the pool). Put only one Repeater on the back columns on every pool row (use Lily Pads first). Change the Repeaters on the pool to become Gatling Peas Put Torchwoods in front of the Repeaters and Gatling Peas (on the pool use Lily Pads first). Then, give the space a column and plant the Magnet-Shrooms on the lawn only. Wake them up with Coffee Beans. In front of the Magnet-Shrooms on the lawn, plant the Tall Nuts. Note: Plant the Tangle Kelps on the last time. The layout should appear as follows.

R R T <> M N

R = Repeaters
G = Gatling Peas
T = Torchwoods
K = Tangle Kelps
M = Magnet-Shrooms that have been awakened
N = Tall-Nuts

Select the following plants (at least eight slots required): Marigold, Pumpkin, Lilypad, Wall-Nut, Magnet-Shroom, Gold Magnet, Doom-Shroom, Coffee Bean. Fill the rest of the slots with plants of your choice. Use the following layout. Note: Put Pumpkins on the first three Marigolds starting from the Wall-Nut, except the Marigold on the pool. Do not put any Pumpkins on the pool. Then, start the onslaught. If you have sufficient sun power, put a Doom-Shroom in to replace with thing in the two Gold Magnets, then awaken the Doom-Shroom with a Coffee Bean.
