Zora Land with a side of eggs

You should make sure you have at least 4 empty bottles before you atempt this next part. Now that you have the Hookshot, you can skip the underwater area of the pirate's fort when you want to get back. Just goto the first switch that you had to jump on as Goron Link, and use the Hookshot to get aross. The next thing you have to do is collect 7 eggs in your bottles. There are 4 in this fortress area. The first egg can be grabbed by going back to the room where you got the Hookshot. You can knock guards out with arrows or the Hookshot if they get too bothersome. Aim for the wooden plank above the tank with your Hookshot and shoot it to get up there. Grab the egg that is in the bottle, but watch out for the snapping clam. Another egg is in a door high up and by where you first entered this inner fort area. Use the Hookshoot a few times to get up there. You will need to fight a little wimp boss. Boss: Red Female Pirate 2 slashes with the level 3 sword and she is gone. Hit the wooden plank with the Hookshot, then shoot all the dead fish inside with arrows before diving in and grabbing the egg in another of your bottles. The 3rd one is towards the back of the fortress. Use the Hookshot to go up a ledge like you did for the last one. Another mini-boss fight guarding the room with the egg. Boss: Green Female Pirate This one takes 3 slashes instead of 2. Watch out for the spin attack that will knock you out and kick you back outside. Grab the egg in the tank, just like the first one and hop back out. The last egg is right by the second one. Go back to the door from the inner fort map that lead to the second egg, turn around, and shoot another Hookshot post on the other side to go up to it, and knock the guard out. In the next room, the chest is a fake. Knock all 3 of the guards out, then jump down and go up the other side. Boss: Pink Female Pirate Barely worth mentioning. Hurt her badly for even trying, then go onto the next room and grab this egg just like you did the others. After you have all the eggs, goto the lab on the first map of Great Bay. There is an owl statue outside, and it is in the water by where you got the Zora mask. Talk to the guy in there, then climb the ladder next to him and drop all the eggs in. Next, look for 2 blocks on the map of Great Bay. They are by where you found the Pirate Fortress. Swim over to these and walk through them (inbetween). You will be in another area where you must follow the signs to get through a mini maze. If you mess up, you will start over. Dive down and go straight from the start to a sign. Go in the dirrection that sign is pointing and walk past the next one you bump into. Walk until you see another sign and follow that one to the next. Turn, and take that one to the next one. Look around from here and you should see a sign nearby. Walk over to that one, and then the dirrection which it points to. You will now need to fight the eels in the huge sea crater before you. They live in holes at various heights in the crater. To hit them, wait till they come out and use Zora Link's barrier attack (The R button). Some of the eel holes will have eggs for you to bottle up in them. Get the 3 eggs from here, and take them back to the lab like you did the other ones. When you drop them in the tank and jump down, all 7 will hatch and the tadpoles will write out some notes. Talk to the man, and target him. Use your Ocarina as Link, and he will comment that it didn't seem to work. Put on the Zora mask, then play it again. You will learn the song that the tadpoles wrote out, which happens to be the Bossanova of the Sea's Roar.
