Zora's Domain/fountain

Do: Enter Jabu Jabu, get to another fairy fountain
Get: Farore's wind
Meet: Kig Zora, Jabu, great fairy

From here, go to the royal chamber. Speak to king Zora, then L-target him, then show him the letter in the bottle and he will (slowley) move aside, revealing the alter of Jabu Jabu. Before you go you need a fish. Go to where most of the torches you lit was (it is near the waterfall). Go to that shallow area and go to the small rocks and bottle a fish. Then go back up to the royal chamber and go down the right path to get behind King Zora and get to Jabu Jabu. When you are in Zora's Fountain, don't give Jabu the fish yet, swim behind Jabu and eventually you will find an island with trees and rocks. Get on it and bomb the rocks, it may take a few tries, but you will blow the rocks up eventualy revealing a pass. Walk through it to find a fairy fountain. Here she will give you the farore's wind. After that, go back to Jabu Jabu, get right up close to him, and give him the fish. He will suck both the fish and YOU into him. (I told you right before the Deku Tree dungeon that a dungeon would be in Jabu Jabu' belly.)
