Level 3-3

Level 3-3 is the twenty-third Plants vs. Zombies level and the third 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 Tangle Kelp.

Difficulty

 * The player has to deal with Snorkel Zombies, which absorbs 10 normal damage shots before dying and (currently) avoids all attacks unless it eats something from the lawn.
 * At the same time, pool lanes are generally weaker than grass lanes.

Strategies

 * Suggested plants:
 * Sunflower
 * Potato Mine
 * Repeater
 * Wall-nut
 * Lily Pad
 * Squash
 * Plant Sunflowers first and collect as much Sun as you can in the beginning of the level. Like most Daytime Levels, plant Potato Mines to stall more time to collect Sun and kill off the first few Zombies.
 * The fourth Zombie that comes is the Conehead Zombie. Conehead Zombies will continue appearing.  Plant Repeaters on every grass lane while starting to plant Lily Pads and Repeaters on Pool lanes.
 * To make the level end faster and easier, plant as many Repeaters as you can evenly on every lane.
 * As the walkthrough suggests, plant Wall-nuts, Squash, or other really inexpensive plants on Lily Pads on the 4th or 5th column from the left to easily fight off Snorkel Zombies.
