Looks like the zombies gave up attacking your front yard. Now they are trying your backyard. And to top it all off, you can't even use your mushrooms! 'cause they fall asleep during the day! Well isn't that just dandy!

One (two after first time)
Level 3-1 is the twenty-first level in , Plants vs. Zombies , and Plants vs. Zombies: Journey to the West , and it is the first Plants vs. Zombies: Great Wall Edition Pool level. It is a regular level. When this level is finished for the first time, the player obtains the Squash.
The player may find it difficult planting Lily Pads on pool lanes.
Mushrooms fall asleep during the day, making them useless in Pool levels until the player unlocks Coffee Bean.
Zombies may overwhelm players in the pool lanes.
A few zombies will randomly pop out of the water during the final wave.
Plant Sunflowers first. Only worry about Lily Pads when the first Ducky Tube Zombie appears. For the first and second zombie that comes on the screen, plant Potato Mines to easily get rid of them.
Plant Peashooters and Repeaters for defense. Start planting Lily Pads and plant there also.
Plant Wall-nuts and Cherry Bombs if necessary.
Plant Snow Peas only when you are done planting Repeaters and Peashooters.
