The Poe Sisters are mini-bosses from The Legend of Zelda: Majora's Mask. Encountered in the Spirit House of Ikana, they are part of an optional sidequest. The Ghost Hunter is holding the Poe Sisters in the backroom, and is the one who sets up the challenge for Link. If the hero accepts, the Ghost Hunter allows him into the backroom, where he battles the four Poes. Link is given three minutes to defeat all four of them. If he can do so while maintaining at least three full Heart Containers, he will win a Piece of Heart.
