Island Clouds

Island Clouds (島雲, Shimagumo) are a special type of clouds. They are fluffy, but dense enough to carry all kinds of things. They form islands in the sky seas, and first appeared in Chapter 239 and Episode 154.

Island Clouds, as well as Sea Clouds, are created when an element contained in the Kairoseki called "pyrobloin," are ejected into the air by volcanic eruptions, comes in contact with water vapors. The density of the water vapors determines whether the Sea Cloud or Island Cloud will be created.

At the cloud cutting factories in Skypiea, they are cut and further processed into artificial cloud products, such as Milky Roads, chairs, etc.
