Golden Feather

The Golden Feather is the spoil of the Pea Hat and the Kargarok in The Legend of Zelda: The Wind Waker. If 20 of these are given to the Rito soldier on the second floor of Dragon Roost Island, who wants to give them to his girlfriend as a gift, he will give Link a "Thank You" letter and eventually a letter with a Heart Piece inside in return.
