Level 3-1

"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!"

- Crazy Dave

Level 3-1 is the twenty-first Plants vs. Zombies level, the eleventh Day level, and the first Pool level.. To complete this level, the player must not let the zombies into his or her house. When the player is finished with this level for the first time, he or she earns the Squash.

Difficulty

 * The player may find planting Lily-Pads on pool lanes difficult.
 * Night-time plants (Shrooms) fall asleep during the day, so they may be very difficult.

Strategies

 * Suggested plants:
 * Sunflower
 * Peashooter
 * Repeater
 * Wall-nut
 * Cherry Bomb
 * Potato Mine
 * 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 laying down the Lily Pads and plant there also.
 * Plant Wall-nuts and Cherry Bombs if necessary.

Trivia

 * Zombies will always spawn more on the grass than the pool.
 * Therefore, pool lanes will always end up being weaker.
