Level 3-9

Level 3-9 is the twenty-ninth Plants vs. Zombies level and the ninth 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 receives a note from the zombies.

Difficulty

 * The player has to deal with the new Bobsled Zombies. They are difficult to get rid off since they travel on an almost damage-resistant sled on the Zomboni's ice.  Although they only take 10 damage each for them to die, there are four of them, which means it takes 40 normal shots for all of them to die.

Strategies

 * Suggested plants:
 * Repeater
 * Torchwood
 * Lily Pad
 * Squash
 * Potato Mine
 * Jalapeno
 * Sunflower
 * Wall-nut/Tall-nut (if you have eight slots)
 * Plant two rows of Sunflowers with Potato Mines to finish off the beginning zombies. Once you have enough sun, plant two or three columns of Repeaters on every lane, pool lanes included.
 * Plant a Torchwood in front of all of the Peashooters to double the amount of damage caused to zombies.
 * Plant a Wall-nut in front of all the plants to protect them from all zombies except Zombonis.
 * Use a Jalapeno to destroy ice lanes so that the Bobsled team will not show in the level.
