I'm in the lake part. After the mountain, and I'm stuck. I can't figure..

Ok I will explain how to get to the entrance from the castle drawbridge in Hyrule Field. First walk towards the little stone bridge that you crossed to head to Kakariko Village for the second stone, you will see a little river, follow this river to the right until it spreads out to be wider. Up ahead you should see a little entrance, cross through the river over to this entrance and head through. You should now be in front of a bunch of boulders and the owl will be sitting on them unless you have already been here in that case they may be gone. After talking to the owl you will hear that Zora's Domain is up ahead. When you look to the left you should see a little chicken. Pick up the chicken because he will be useful if getting to the domain. So pick him up and head forward to the fence and jump to the right and then back to get past the fence. Head along the path until you get to a log and go up the ledges in front of you working your way to a bridge. Cross this bridge and then you should be looking at a bunch of different pathes in front of a waterfall. Go up the pathes so you are right in front of the waterfall standing on a peice of something on the ground. Play Zelda's Lullaby and the waterfall will stop and you can jump forward into the entrance to Zora's Domain. Head to the back of the domain and go up the stairs to this room where a big weird looking guy is sitting. This is King Zora and if you go talk to him he will tell you that his daughter Princess Ruto is missing. Quickly head to Lake Hylia by taking a shortcut, if you head to the left out of the room you will see a zora standing at the top of a waterfall, play his little game so you can get the prize which you will need. Jump down the waterfall into the water and right in front of you below the water should be a little square entrance, swim through here and then you should be at Lake Hylia and you will see that there is something in the water right in front of you. Z-target it and then swin down and pick it up. Take the bottle back to King Zora and he will say that you can go rescue Princess Ruto. Take that new empty bottle and go down below and scoop up a fish into it. Then go back to the King and go behind him. Right away you will see a huge fish called Jabu-Jabu, drop the fish you caught right in front of him and he will suck you in. Now you are in the temple. Good luck!!!
