Don Gero's Mask

Don Gero's Mask is a frog-shaped mask found in Majora's Mask, bearing the image of Don Gero, the conductor of the frog choir. It allows Link to communicate with frogs around Termina to let them know that the Frog Choir is getting together to sing again. This can only be done after defeating Goht and spring returns to Snowhead. The frogs are located in Clock Town's Laundry Pool, the Woodfall Temple (after defeating Gekko), the Mountain Village, the Great Bay Temple (after defeating Gekko), and the Southern Swamp near the Big Octorok. Getting all five frogs to the choir will earn you a Piece of Heart.

Obtaining the Mask
To acquire the mask, Link must light all the torches lining the wall of the Goron Shrine using a Deku Stick before defeating Goht (the Bunny Hood makes this task significantly easier, but is not necessarily required); alternatively, Link can light them at once by shooting a Fire Arrow to the torch at the center of the chandelier of hanging pots on the ceiling. Doing either action will make said chandelier to spin. Link must then use the Goron Mask to roll off of the ramp on the top floor to collide with the pots until some Rock Sirloin falls to the floor. He must bring this to the Mountain Village (therefore having to avoid any enemy encounter) and give it to the Goron standing on a ledge who is hungry. He will thank Link with the Don Gero's Mask.

The Happy Mask Salesman says the mask has an "operatic feel."
