Moosh's Flute

From Zelda Wiki.org

Moosh's Flute is a Flute used to summon the flying bear Moosh to help Link in the Oracle Series. The Flute is obtained in Oracle of Seasons from the shop in Horon Village, at which point it's called a Strange Flute. Once Moosh is rescued, he will identify the Flute as Moosh's Flute. If nothing extra is done in Oracle of Ages, Link will always receive Moosh, who will become his pet for the game.
