Survival: Pool (Hard) is the eighth level of Survival Mode in Plants vs. Zombies, Plants vs. Zombies: Journey to the West, and Plants vs. Zombies: Great Wall Edition. Being set in the pool, it contains ten waves of zombie hordes divided by two flags for each and for every two flags survived, and the player will be given a chance to strategize by changing the set of plants they chose from the beginning of the previous waves.
Any normal Pool strategy will work here. Alternatively, you can use any Survival: Endless strategy that can survive at least ten flags. You can use many strategies, but a fire pea strategy works particularly well. Use Repeaters or Gatling Peas and plant Torchwoods in front of them. Try to get Cattails and Cob Cannons, too. Eliminate the harder zombies with Spikerocks and place Pumpkins on your front row of shooters to watch out for Imps.
