Instructions
Get Giant's Knife in Zelda: Ocarina of Time
Travel through Kakariko village to reach Goron City.
Go to the bottom floor to play Saria's song to King Darunia using your ocarina. He will give you a bracelet that allows you to handle bomb flowers.
Leave King Darunia to travel above the first floor. You will see a cracked wall near bomb flowers. Throw the bomb flowers at the cracked wall. When you blow up this exterior wall, you will find another wall behind it. You have found the correct hallway.
Blow up the cracked wall (located behind the exterior wall) until you reach a large Goron. When you talk to him, he will inform you of a weapon he is working on.
Complete your missions as young Link and travel into the future to the Temple of Time. Go back to Goron City as an adult to talk to the giant Goron. He will give you the Giant's Knife.
