About The Fairy
Tatl is a character from The Legend of Zelda: Majora's Mask. She is Link's fairy companion throughout the game. She is the sister of Tael.
As a Fairy companion, Tatl is not as informative as Navi from The Legend of Zelda: Ocarina of Time and has somewhat of an attitude, however, her intentions are good. At first, she is cold and callous towards Link, but eventually grows fond of him, much like Midna. She functions the same way as Navi when it comes to Z-targeting and giving Link pointers when he needs it. Unlike Navi, who tells Link about enemies encyclopedia-like, Tatl often interjects her own opinions into her information (when telling Link about the Stalchilds, she says that they are cursed and adds "What are you going to do about it?"). She also seems surprised about Link's lack of knowledge when asked about enemies that appeared Ocarina of Time as well as Majora's Mask. Tatl's voice is represented by chiming noises, due to her complaints. Some people like Tatl better than Navi, due to her chime instead of going,"Hey! Listen!" Others find her more annoying because she is rude, for example, calling Kafei "careless, just like (her) partner" which may be insulting to both Link and Kafei, even though they take it quite well considering that Tatl instulted them both.
The siblings' names appear to be a play on "tattle-tale", due to their childlike mischief. Tatl is also a play on the Fairy's method of giving information on enemies.
