|Nautica, Mermaid near the Church||Gracos's Trident|
Once you’ve spoken to the Queen of Nautica for the first time and obtained the Green Orb, head out of the Church to find a mermaid with a request for you. She wishes to hear a song she heard a long time ago from a young boy.
Zoom over to Gondolia and head to the north-west tower where you can find an old man. Time has passed since the mermaid last heard that song and the boy is now an old man. Speak to him to have him teach you the song he once sang before Zooming back to Nautica to deliver the song to the mermaid.
