Don Gero's Mask

Don Gero's Mask is a frog-shaped mask found in Majora's Mask, bearing the image of Don Gero. 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 once spring returns to Snowhead. The frogs are located in Clock Town's Laundry Pool, Woodfall Temple (after defeating Gekko), Mountain Village, Great Bay Temple (after defeating Gekko), and Southern Swamp near the Big Octorok. Getting all five frogs to the choir will earn you a Piece of Heart.

Obtaining the Mask
Before defeating Goht, all the torches lining the wall of the Goron Shrine must be lit up using a Deku Stick, although the Bunny Hood is not necessarily required. This will cause the hanging pots on the ceiling to begin spinning. Link must then use the Goron Mask to roll off of a ramp on the top floor to collide with the pots until some sirloin rock falls from a pot. He must bring this to the Mountain Village and give it to the Goron standing on a ledge who is hungry. He will thank Link with the Don Gero's Mask.
