Sky City (天空之城; pinyin: tiānkōng zhī chéng) is the ninth world in the Chinese version of 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 left to the level progress bar. The ship has a cannon that targets zombies automatically. There is a new power-up right to the Cuke that briefly controls the cannon by firing a lot of bullets where aimed to, but it has a cooldown time.
Another mechanic are the lightning attacks. Each pair of bolts will strike a single plant, causing negative effects. The lightning bolts have two types: the positive charge ones and the negative charge ones. The kind of negative effects depends on the bolts' combination. If both are positive charges they will deal continuous damage on the plant; 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. However, Anthurium can absorb the bolts without being affected, turning them into damaging projectiles, and it reverts other plants to normal 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 air.
While it is unknown which time period this world is based on, it looks to be based on World War II, as the game has revealed that it is based on the US Air Force. However, jetpacks were invented after World War II. This means it may be based on the future, but likely earlier than the Far Future period, possibly World War III.
This is a vast endless sky. Clouds there are filled with dangerous lightning. Zombies are driving all kinds of dangerous weapons. You will meet an unprecedented challenge. Watch out or you will be gunned down!
In Chinese: 这是广阔的无尽天空, 云层中满是危险的雷电。僵尸们驾驶着各种危险的武器, 你将遇到前所末着的挑战。当心不要被击落！
Don't get fooled by the fact it's rated 3 Jalapeños. It is an extremely difficult world. The main reason is the fact that there's no Lily Pad/Flower Pot like plant that allows you to place non-flying plants in the sky, heavily restricting strategies. The lightning gimmick can easily screw up your defenses quickly. The unique zombies aren't a cakewalk either. Air Raid and Across the Lawn Brain Busters are insanely hard, although One Gun Guard is very easy. The boss, the Zombot Vulture Fighter is extremely difficult to beat due to summoning powerful zombies and conducting powerful attacks that can easily destroy many plants at once. Many players consider it the hardest world for these reasons

One Gun Guard
- Main article: One Gun Guard
One Gun Guard is the first exclusive Brain Buster in this world. In it, the player controls a machine which fires lasers at the synchronized patterns of flying zombies. The goal is to gain enough points to pass the level, and in that sense, it is similar to Cannons Away, but it does not have a progress bar so you can shoot as many zombies as you want and aim for the best moment for shooting the most zombies. The player will lose if he has no sun left.
There are 2 guns that cost 25 and 125 sun each. In the Hard version of each level, there is an additional gun which does damage to multiple targets that costs 225 sun.
- Main article: Air Raid (PvZ2C)
Air Raid is the second exclusive Brain Buster in this world. Player can choose between three plant teams. If player collects certain amount of points during level, the plant upgrades by itself. If player does not have at least one plant in team, then this team is not available (though Team Pea is always available).
Across the Lawn
- Main article: Across the Lawn
Across the Lawn is the third exclusive Brain Buster in this world. Its concept is extremely similar to Fright Theater. The main change is that now there is a trail of arrows representing the path where zombies go and it can be changed by placing wooden boxes. However, they can only be placed on determined tiles and cost 100 sun each. The rest is almost the same. The player has to place certain plants already chosen on metal and wooden crates and upgrade them with sun that every zombie drops to get ready for menaces with enormous quantities of health without letting them reach the end of the pathway. There is also a limit of how many zombies can get to the goal and the level is lost when that limit is exceeded.
Plants vs. Zombies Wiki has a gallery for Sky City.
- See Sky City/Walkthrough.
- It is the second China-exclusive world, with the first one being Kongfu World.
- Its Chinese name is Castle in the Sky.
- Sky City got its official English name in the 1.8 update. It is based of the world's internal name "sky_city".
- There are no lawn mowers present, due to the new gameplay style.
- Rotobaga is found in this world. This and Endurian are the only monthly special plants from the international version to not be found in their respective worlds.
- This is also the only monthly special plant to be obtained normally later.
- It is the fourth Chinese world without Save Our Seeds levels.
- Most likely because the zombies can’t reach the plants that aren’t in the sky.
- It is the fifth world in the Chinese version without Locked and Loaded levels.
- It is the fourth world to have no returning plants from the first game, the other five being Kongfu World, Frostbite Caves, Lost City, Jurassic Marsh, and Modern Day.
- It is the first world since Far Future to have upgrades.
- Blover, E.M.Peach, Bamboo Shoot, Freeze Mushroom, Sap-fling, Jackfruit, Snow Cotton, Agave, and Hurrikale cannot be chosen in this world. For some reason, the player can take the locked plants in the Zomboss fight.
- The reason for Blover and Hurrikale is because they blow away flying zombies and all zombies found in this world fly, meaning that the player would easily beat this world. However, when battling Zomboss, the player can choose them, Blover will not affect zombies but Hurrikale will just push them away and slow them.
- The reason for E.M.Peach is because it would stop the zombies' machines from flying as it would shut the zombies' flying machines down, meaning the player would easily beat this world.
- The reason for Bamboo Shoot is because it attacks by burrowing into the ground, meaning it would either cause glitches or have limited to no use.
- The reason for Freeze Mushroom is because its Plant Food effect involves creating giant sinkholes, which would either cause glitches or not work in this world.
- The reason for Sap-fling is because it throws sap onto tiles, slowing zombies down, and most of the lawn is not made of tiles that sap can land on.
- The reason for Jackfruit is because it rolls on the ground, causing it to fall and have no use since most zombies are airborne.
- The reason for Agave is because its Plant Food effect involves making a dirt lane attack that effects the ground, meaning it would either cause glitches or not work properly.
- Guacodile can be chosen, since it can still use its normal attack if the zombies cannot reach it.
- The reason for Snow Cotton is that it summons snowmen to jump on the ground which is useless since they will jump off the ship and fall down, rather than hitting the zombies.
- Pumpkin Witch can also be chosen in this world, but it will not attack the zombies.
- Freeze Mushroom is given inside levels 10 and 16, despite the fact that Freeze Mushroom is disabled in the rest of Sky City.
- It is because that those are Air Raid levels, and Air Raid levels does not let the player use Plant Food, which is the reason why it is disabled.
- For some reason, Fire Gourd's Plant Food effect can damage the ship.
- There's an error with the music in the iOS version. It only plays once and then stops for the rest of the level, leaving the level with no music. It was fixed in an update.
