Keaton

Keatons are yellow foxes with 3 tails that appears in Majora's Mask. Too get them to appear, you need Keaton's Mask and to cut some Moving Grass 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 Majora's Mask. If you answer them all right, you will get a Piece of Heart.
