Location and Uses
After Link completes the Dragon Roost Cavern, Baito can be seen wandering around Dragon Roost Island trying to apply for the Letter Sorting job. He is eventually hired at the Island Postal Service after Koboli, impressed by Link's contribution to the mail sorting, decides to hire a permanent assistant. Baito then allows Link to sort letters as a mini-game. If Link manages to sort 25 or more letters, Baito will ask him to put the Note to Mom in the mail. The letter talks about how great Link is.

Some time after sending the letter, Link will receive a reply from Kashiko, Baito's mother, with a Piece of Heart inside.
