Fairies are tiny creatures that are found all throughout Hyrule in Great Fairy Fountains or Dungeons. Catch them in a Bottle and use them to restore your health, or keep them to use as life insurance. When you lose all of your hearts and you have a fairy in your inventory, you will be completely revived and revitalized. When you are about to face a boss, break some nearby pots to try and flush one out. It's always a good idea to have one just in case.
