Fabulous Five Froggish Tenors

In Ocarina of Time, there are five frogs that can be located underneath Zora River. By standing on a protruding log and playing the Ocarina, the frogs start croaking to your tune. A successful tune engages a sudden growth spurt in one of the frogs, and the group promptly awards Link with 50 rupees. Once all five frogs have grown, a mini-game can be activated where the player must follow the tune which the frogs play, in order to make them leap to catch the butterflies suspended above their heads. The reward is a Heart Piece. Also, playing the Song of Storms for them also rewards you with a Heart Piece.
