"You got the Captain's Hat! Wear it with (C)."
In Ikana Graveyard, Link finds Captain Keeta in his dormant state. To awaken him, Link must play the Sonata of Awakening, which causes Captain Keeta to awaken and challenge Link to a battle. After Link completes the challenge, Captain Keeta rewards him with the Captain's Hat. With the Captain's Hat, Link can be mistaken for Captain Keeta by the Stalchildren, which allows him to talk to and be respected by them.
