Don Gero's Mask (ゲーロのお面, Gero no Omen?) is one of twenty-four masks in The Legend of Zelda: Majora's Mask. It looks like Don Gero and is used to talk to frogs. These frogs form the Frog Choir, similar to the Fabulous Five Froggish Tenors from Ocarina of Time. By reuniting all five members of the choir, Link can get a Piece of Heart. Two of the frogs have been transformed into hostile Gekkos that Link must defeat in order to turn them back into their normal selves. As for the other three, one of them is in the Laundry Pool in Clock Town, one of them is on a log in the Southern Swamp, and one of them is near the Mountain Smithy (it only appears once Goht has been defeated and spring has returned to Snowhead).
