Keaton

Keatons are yellow foxes with 3 tails that appears in Majoras Mask. Too get them to appear, you need Keaton's mask and to cut some grass which moves when you have cut one of them, for example the grass in North Clocktown. You must have Keaton's Mask on when you cut the grass! The Keaton will then appear and ask you some questions about things in the game. If you answer them all right, you will get a Piece of Heart.
