What is a Floating Island?

Floating Islands are structures made of Dirt Blocks and Rain Clouds that float high above the world and can even be found in space. These structures can be vulnerable to certain enemies in Terraria, such as Harpies in Pre-Hardmode, and Wyverns and Arch Wyverns in Hardmode.

A Floating Island consists of a structure made using Sunplate Blocks, Disc Walls, and Glass Walls. Invariably, it’ll hold just a single Skyware Chest and various Skyware furnishings randomly placed. The arrangement will feature three or five background walls placed between each window.

In world creation, they appear randomly in the top sixth of the map and become infected by evil biomes if affected by transformation during Hardmode. However, non-corrupted ones can become a suitable residence for NPCs by adding a light source.

Fishing

Floating Lakes are bodies of water lacking the Sunplate Block structures and their contents. It’ll only appear when all of the Floating Islands in Terraria have spawned. Therefore, if there’s at least one lake in the world, you can expect 3/5/6 Floating Islands to be present, depending on whether the world is Small/Medium/and Large.

It’s a rare occurrence to find Water Chests within Floating Lakes. It’s also perfect for fishing in Terraria. Occasionally, Floating Lakes may be positioned too close to the ground to be suitable for sky fishing, resulting in surface fishing catches instead. This occurrence is more probable in Large worlds.
