Floating Island

A floating island is an airborne structure that can appear in the overworld, floating up in the clouds.

Floating islands generate in the overworld in any biome. The height of the floating island is dependent on where it generates, meaning that floating islands generated in ocean biomes will be lower than that of ones generated in mountain biomes.

Floating Islands are made up of skyrock and glowers, a block and plant that are unique to floating islands. Floating islands have four set forms that they can spawn in, with three of them housing an encased diamond in the center of them. These forms are less common as they get bigger, and are as follows:
