Castle in the Sky

Castle in the Sky is the ninth world in Plants vs Zombies 2: It's About Time (GMXX Version). It is unlocked using the World Key from Frostbite Caves Day 8. It has a total of 29 levels, 9 plants, and 2 upgrades. It takes place in 1941, during World War II. After Day 8, the player receives a World Key, allowing them to unlock Silent Suburbs. This world is in the sky, and certain parts of the lawn can't be planted on, so flying plants must be used. Another gimmick is lightning strikes. There's 2 kinds of lightning: Red Lightning, which damages the plant it hits, and Blue Lightning, which stuns the plant it hits. If Red Lightning and Blue Lightning hit the same plant at the same time, the plant will be slowed down. Additionally, the Anthurium can absorb lightning strikes around it to amplify it's attacks. The Lawnmowers of this world are modeled after Biplanes. The boss of this world is the Zombot Maelstrom Vulture.

## In-game Description

*In the year 1941, the world is at war. In an enormous aerial battle, you must use both your wits and your airborne plants to deal with the dangerous zombies!*

## Gimmicks

* Lightning Strikes

Lightning Strikes occur at random times during levels. There's 2 types: Red Lightning and Blue Lightning. Red Lightning damages plants it hits, while Blue Lightning stuns them. On the rare occasion that both hit a plant at the same time, the plant is slowed down. The Anthurium is immune to lightning strikes, however, and can absorb nearby lightning strikes to amplify it's attack.

## Surprise Attack

The surprise attack of this world is called *Look Out Below!*

When it happens, a bunch of Pilot Imps parachute down onto the lawn.

## Plants

There are 9 plants that can be obtained in this world, 1 of which returns from the original Plants vs Zombies.
