Frog Choir

The Frog Choir is a group from The Legend of Zelda: Majora's Mask. As its title implies, it is a choir that consists of five frogs native to Snowhead and their mysterious conductor, Don Gero. Because of the perpetual winter in Snowhead due to the Skull Kid's magic, the members of the Frog Choir have been forced to relinquish from Snowhead. A certain sidequest in the game requires Link to hunt down these five frogs and speak with them while wearing Don Gero's Mask. By doing this they promise to return to Snowhead when spring arrives, i.e. when Link defeats Goht.

Frog Choir sidequest
When Link visits the Mountain Village in Snowhead, he sees a hungry Goron stuck atop an ice outcropping. Because the Goron is so hungry, he does not have the willpower to return to Goron Village and get some food. If Link, however, retrieves Rock Sirloin from the chandelier in the Goron Shrine, he can bring it back to the hungry Goron. As thanks, the Goron gives Link the mask he is wearing, the Don Gero's Mask, and rolls back to Goron Village. With this mask, Link can communicate with the frogs scattered throughout Termina and demand they return to Snowhead when spring arrives.

One frog is found in Clock Town's Laundry Pool, another is found atop a log in the Southern Swamp that Link passes while on the Swamp Boat Cruise, and a third is found in the Mountain Village near the Mountain Smithy. The remaining two frogs have undergone a type of mutation that has turned them into hostile creatures called Gekkos. In order to return them to their normal selves, Link must defeat the Gekkos, and they will morph back into normal frogs; one Gekko is found in Woodfall Temple while the other is found in Great Bay Temple.

When Link has spoken to all five frogs in a single three day cycle, he can visit the pond in the Mountain Village to listen to their performance. When he does so, he is given a Piece of Heart.
