Sky City is the 11th world in Plants vs. Zombies 2.The main feature of this world is that zombies will no longer rush into the player's house, but instead, they will attack Crazy Dave's ship until it is completely destroyed. The health of the ship is displayed to the left of the level progress bar. The ship has a cannon that targets zombies automatically. There is a new power-up that briefly controls the cannon by firing a lot of bullets where it is aimed to, but it has a cooldown time. Another mechanic is the Thunderbolt attack. Thunderbolts will strike plants, giving them positive and negative charges depending on the lightning type. When a single plant has been struck twice, this will cause negative effects. The thunderbolts have two types: the positively charged and the negatively charged. The kind of negative effects depends on the bolts' combination. If both are positive charges they will deal continuous damage on the plant until it dies; if both are negative charges, they will totally stun the plant, and if they are mixed they will cause the plant's attack speed to reduce by 50%. However, Anthurium can absorb the bolts without being affected, turning them into damaging projectiles. It also reverts other plants to normal if two plants within a 3x3 radius of it have matching charges, as well as through using its Plant Food ability. Also, in this world there are only three columns where ground plants can be used, on the other ones flying plants are the player's only choices. This is similar to Big Wave Beach, as the player cannot plant on water, but unlike Big Wave Beach, there are no plants that will enable the player to plant ground plants in the air.
