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 the 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:
 * Snow Pea or Repeater
 * Potato Mine
 * Lily Pad
 * Squash
 * Tall-nut
 * Jalapeno
 * Sunflower
 * Spikeweed
 * Plant two rows of Sunflowers with Potato Mines to finish off the beginning zombies. Once you have enough sun, plant one column with extra Repeaters in pool on every lane.
 * Plant Tall-nuts in water and Spikweeds in front of all of the Snow Pea or Repeaters to kill the zombies caused to zombies.
 * Use a Jalapeno to destroy pool lanes.
