Road To Great Bay Temple
Remember the picture of a pirate of took? Well go to the fisherman's hut in Great Bay and he will trade it for a seahorse. Now release the seahorse in the water and follow him until you reach pinnacle rock, in here there are eels which you can simply take out but electrifying them with the Zora mask. Now only three of these eels will have the 3 zora eggs, but if you defeat all of them you will gain a piece of heart. Once you've collected all seven Zora eggs and put them in the Marine Biology Lab (the building in the water) they will teach you a song that lets you enter Great Bay temple. Now in the middle of zora cake is a stone formation that looks like a giant fish you can go in its mouth to enter zora hall.Now go through the hallway in Zora hall and take a left to find that lulu is sulking, play the song you just learned. As this will open up the temple for you. Now just hookshot on the turtle’s back and go to the temple.
