Tatl is Link's fairy companion in Majora's Mask. Due to several fans' annoyance with Navi, her counterpart in Ocarina of Time.
Tatl and her brother Tael, in the beginning of Majora's Mask, are both aides to the Skull Kid. After a twist of fate, Tatl gets seperated from her brother and decides to team up with Link until they can find the Skull Kid, and ultimately, Tael.
