Pocket Egg: Get this from the "Cucco Lady" in Kakariko Village. Play the Sun's Song twice to make the egg hatch. Then go into the house right next to the house that has the man sitting on top of it. You will see Talon there asleep, again. Stand over him and use the Cucco. He will wake up. Take the Cucco back to the "Cucco Lady" and she will give you a blue cucco, Cojiro.

Cojiro: Take this to the Lost Woods. From Kokiri Forest, enter the Lost Woods and go one room to the left. Use Cojiro next to the man sitting by the stump. He will give you the Odd Mushroom.

Odd Mushroom: Take this to the potion shop in Kakariko Villiage. She will make an Odd Potion.

Odd Potion: Take this back to where the man was sitting in the Lost Woods. A little Kokiri girl will be there. Give her the Odd Potion and she will give you the Poacher's Saw.

Poacher's Saw: Take this to the man outside the carpenter's tent in Gerudo Valley. He will give you the Broken Goron’s Sword.

Broken Goron’s Sword: Take this to Biggoron, who runs the Sword Shop on top of Death Mountain near the entrance to the Great Fairy's Fountain and Death Mountain Crator. He will give you the Perscription.

Prescription: Take this to King Zora in Zora's Domain. He may need to be unfreezed. If this is the case, get some Blue Fire from the Ice Cavern and unfreeze him. He gives you an Eyeball Frog.

Eyeball Frog: Take this to the Lakeside Labratory at Lake Hylia. Give it to the scientist inside and he will give you the Biggoron Eye Drops.

Biggoron Eye Drops: Take these back to the Biggoron on top of Death Mountain that gave you the Perscription. He will give you a Claim Check for the Biggoron Sword.

Claim Check: Play the Sun's Song SIX times to make 3 days pass. Then present the Claim Check to the Biggoron and he will have finished your sword and give it to you. This sword is twice as powerful as the Master Sword and doesn't break like the Giant's Knife does. It is so massive, Link needs to use two hands to hold it, meaning he can't use the sword and a shield at the same time.
