Keaton (Ocarina of Time/Majora's Mask)

Keaton, also known as the Ghost Fox, is a character from The Legend of Zelda: Majora's Mask. Although it is mentioned that Keaton is an entire race, it is unknown if the Keaton that appears in Majora's Mask is the same one or many different Keatons. Keaton is a golden fox with three tails.

Keaton is a wise creature that appears only to those wearing the Keaton Mask; however, it is not fooled by one wearing the Keaton Mask. Keaton rewards honest people if they are able to pass its test, the Keaton Quiz, in which it asks 5-7 questions on varying topics. If Link answers Keaton’s questions correctly, he is given a Piece of Heart.

Origin
Keatons are quite possibly based on the kitsune, a mythological fox from Japanese mythology. The name Keaton itself may be a reference to kitsune, although it is never specified.
