Puff-shrooms are the endangered plants. Because of their gimmick of disappearing after a while, using Plant Food on them is needed to win. Luckily, there is ample supply of Plant Food throughout the level. Saving Plant Food should be kept in order, as mindlessly using it all can easily result in a loss. Jester Zombie and Wizard Zombie can prove to be an annoying pair, as most Area of Effect plants are short ranged. Necromancy can also cause some trouble.
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.
Start by planting one column of Sun-shrooms. Let the Puff-shrooms destroy the graves. When all the graves near them are broken, be ready. When they are about to disappear, immediately use a Plant Food on one of them, because its Plant Food ability also extends their lifespan. Then, plant another column of Sun-shrooms on the third column.
Plant at least two columns of Fume-shrooms and a column of Snapdragons. Then, plant a column of Wall-nuts or Tall-nuts next to the Snapdragons.
Pay attention to the Puff-shrooms. Remember to feed one of them Plant Food regularly.
Use Grave Busters to remove any tombstones on the lawn.
You can launch a lawn mower when this level becomes too hard.
When the Puff-shroom start flashing, you should quickly give the Puff-shroom plant food.
Also, the player can use Puff-shroom's Plant Food Boost, if available, to easily complete the level. However, be careful of Jester Zombies when doing so, as it can deflect the spores from the Puff-shroom and kill them before you realize that mistake.
