Floating Island

Floating Islands are masses of land that appear in the sky. Just like in forests, you can find trees and grass blocks growing over dirt blocks, with some stones and ores in the ground. They have a building made of ore bricks and a chest inside. The quality of the island's ore and chest are believed to be related to the type of brick the building is made of, though this is false. The monsters that spawn here are the same as the ones from the forest, with the addition of the Harpy.



Finding Floating Islands
Perhaps the easiest, method, is to use a map viewer and search for floating islands that way. This is considered cheating, because you’ll have to access save files outside of the game itself. Thus, this will also not work for multiplayer servers where the player does not have access to the map file.



Hints
There are some natural hints which indicate that Floating Islands:
 * 1) Irregularly shaped dirt walls on the surface (shown on the right).  Although not all floating islands have these underneath them, when one is found, it usually indicates a Floating Island.
 * 2) When floating islands are above corruption, you'll see an abnormally high rate of slimes by day and zombies by night. These are falling down from the island above you. This applies to all locations below floating islands, but is more noticeable in areas of the corruption.

Hunting
A quick way to find them easily is to fire a Meteor Shot, or Water Bolt up into the air. If it bounces back a few seconds later, it's almost certain that a Floating Island is above you (note the angle that you fire up at).

Another way to actively detect Floating Islands is to fire a Space Gun into the air, because it gives an acoustic signal when hitting a block. (Note: Only works if you are max. 200 ft. below the Island). If you have enough falling stars left, you can fire them from a Star Cannon into the air and wait until you hear it cut the vines.

Searching
If nothing else helps, you can use a Depth Meter to find the floating islands. They can usually be found at these heights: Then dig lots of blocks and go to one side of the map, making a bridge to the middle amount of height suggested above. After that, head towards the other side.
 * Small map - 430-475 ft. (430-475 ft is your best bet, but some have been known to spawn in the high 500's and high 300's 350-375)
 * Medium map - 500-700ft (650ft is your best bet).
 * Large map - 500-900ft. (You may be able to see a floating island at 450)

Loot
Loot research going on in Floating Islands/Drop research

Chests on a Floating Island may contain a variety of unique items, including 3 items uniquely found there:


 * Lucky Horseshoe
 * Starfury
 * Shiny Red Balloon

Each chest has exactly one of these items. The generator guarantees that for the first 3 floating islands, each will have a different item. After that, the item is chosen at random. The type of wall and brick (copper, silver, gold) is completely random and has absolutely no correlation with the loot found inside the chest.

Enemies

 * Slimes (day)
 * Zombies (night)
 * Harpy
 * Demon Eye (night)
