Big Wave Beach - Day 20

Big Wave Beach - Day 20 is the 20th level in Big Wave Beach. When this level is finished for the first time, the player unlocks the Tiki Torch-er. The tideline is located between the first and second column. This makes the level slightly harder.

Strategies
Created by 
 * Suggested plants:
 * Sun-shroom
 * Magnifying Grass
 * Threepeater
 * Lily Pad
 * Tangle Kelp
 * Sun Bean
 * Cherry Bomb
 * Dig up the two rightmost Lily Pads for extra sun. Plant a full column of Sun-shrooms in the first column. When three zombies appear, drown one with a Tangle Kelp immediately and kill another with a Magnifying Grass. Wait until the Tangle Kelp recharges again, so you can use it to kill the third zombie.
 * Drown the Conehead with a Tangle Kelp and kill the Imp with a Magnifying Grass. Make sure you have a whole column of Magnifying Grasses and use it to kill the zombies, until the first low tide. Once you have enough sun, you can start planting Threepeaters.
 * In the first low tide, three Surfer Zombies will appear. Use a Cherry Bomb to kill at least two of the three along with other zombies and make the last one waste its surfboard by placing a Sun-shroom in front of it. Upon seeing the Buckethead, make it eat a Sun Bean fed with Plant Food to produce a lot of sun.
 * In the second flag, kill the two Surfer Zombies immediately with Magnifying Grasses. In the second low tide, use a Cherry Bomb and launch a Lawn Mower if needed or use Magnifying Grasses to kill the zombies.
 * In the final flag, simply use Magnifying Grasses to kill the zombies.
