Pirate Seas - Day 21 is the 21st level of Pirate Seas in the Chinese version of Plants vs. Zombies 2. 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 gets coins.
In the Normal Mode of this level, the player has to beat 10 kinds of zombies in Level 1.
Difficulty
The player should have no worries on defeating 5 zombies in 5 seconds. However, producing 3250 sun can be challenging. Using Plant Food on sun producers are recommended, as they will make this goal easier. Imp Cannons can be struggling to deal with, but if the player is supplied with powerful plants like Coconut Cannon or a good projectile plant like Kiwifruit, the player should defeat them easily. Swashbuckler Zombies only pose as a minor threat in this level.
