Fairies

The Pink Fairy, Green Fairy, and Blue Fairy are peaceful Critters found in the Surface layer or below which will attempt to lead the player to valuable treasures and Ore deposits. Fairies will only spawn if at least one Fallen Log has been left in the world without being destroyed, otherwise they will no longer spawn independently. The three Fairy variants all function identically.

There is a 1/50 (2%) chance that Fairy will emerge from a shaken tree in the Hallow at Night. These fairies will spawn even if all Fallen Logs in the world have been broken.

Once a Fairy spots a player, they will fly and follow the player for quite a while. If they are within range of a treasure, they will head in that direction and wait for the player to follow. Once the fairy reaches the loot it is trying to lead to, it will disappear in a burst of glowing glitter.

After 5 minutes, if the fairy has not led the player to a treasure and vanished, it will fly off.

On the Surface, Fairies can sometimes spawn near Fallen Logs, and can then be caught with a Bug Net. Fairies found underground, which lead players to the treasure, cannot be caught or hurt.

Treasure detected
Fairies may lead players to several different types of loot:
 * Chests (including already-opened Chests, empty Chests, and player-placed Chests).
 * Trapped Chests
 * Life Crystals
 * Life Fruit
 * Ore
 * Strange Plants

If there is no such loot in the vicinity, a Fairy will follow the player until it detects one.

Tips

 * Releasing a captured fairy will cause it to act like a fairy found underground; it will begin following the player and signal them once it detects treasure. Note that this means any released fairies cannot be captured again. This can be useful for locating chests anywhere in the world, especially if used in conjunction with a Metal Detector.

Trivia

 * The tooltip for fairies, 'Hey! Listen!', is a quote from Navi, a popular Fairy character from.
 * These smaller fairies bear a strong resemblance to those summoned by the Fairy Bell, albeit much smaller in size.
