Pirate Seas - Level 2-4 is the third spin-off level of Level 2-1 of Pirate Seas in Plants vs. Zombies Online. In order to get all 3 stars, the player must not let the zombies trample the flowers or lose any lawn mowers. When this level is finished for the first time, the player will get 5 Snapdragon Puzzle Pieces.
- This is basically the two-plank version of Level 2-2. The waves skip very quickly, compared to Wall-nuts' sluggish recharge. The player needs to quickly set up a proper defense in order to block the zombies from the flowers.
- The strategy should be as same as in Level 2-2. However, there are only two planks, which means even though you have less lanes to majorly protect you still have more zombies to destroy. In other words, you would only have time to plant about 4 Sunflowers in the beginning. Keep planting your defenses, then take care of your sun-producers later.
