Pirate Seas - Day 21

Pirate Seas - Day 21 is the 21st level in Pirate Seas. To complete this level, the player must defeat five zombies in five seconds and produce 3250 sun. When this level is finished for the first time, the player unlocks an upgrade called Extra Seed Slot, which unlocks an extra seed slot for choosing one more plant.

Difficulty

 * All the objectives should not be too hard to success. Just focus on killing the zombies with Coconut Cannons.
 * This should be easy if you try harder.

Strategies

 * See Gallery for more details.

Notes: This strategy is for all versions.
 * Suggested plants
 * Twin Sunflower

 * Do what you need to do first.
 * Try to plant at least three Coconut Cannons to stop the Imp Cannons. This will help you complete the first objective without much troubles.
 * Feed Twin Sunflowers with Plant Food to produce more sun. If things are going to be better, you can plant one more column of Twin Sunflowers.
 * The Spring Bean will also help you finish the first objective if there are too many zombies on the lawn.
 * Wall-nuts are still essential to stop the Swashbuckler Zombies.

Trivia

 * Before the 1.9 update, the player needed to not lose any lawn mowers in order to complete the level.
