Well, there is this Zora Queen behind a waterfall in Hyrule. She is unexplainably bloating because a smooth gem was taken from her pool by a theif. You will find the theif near Saharashla's house. Sneak up behind him as a painting (else he will run away) and confront him. He will tell you he sold it to a merchant in Kakariko Village. Also he will give you his shoes, the PEGASUS BOOTS
