Before going to the Goron Village, go to Lake Hylia (riding your horse or by foot) and visit your old friend Bonooru the Scarecrow. Play for him the song you invented 7 years ago. This melody becomes the Scarecrow's Song.
Goron City
Now go to the Goron Village from Kakariko Village. Once you reach it, go down one floor and you will see a rolling rock. Stop the rock by throwing a bomb at it (good luck!), then talk to the Goron. Ask him about the dragon and the Gorons, and he will give you the Goron Tunic. Wear it, then go down to the first floor, enter Darunia's room and pull the statue.
Note: There is a room with a lava lake east on the map. You can cross this area only using the Longshot and the Song of Time. However you will only find business Dekus there.
Death Mountain Crater
Go left and use the Hookshot to reach the other side of the broken ladder. Keep going and meet Sheik who will teach you the Bolero of Fire. Go ahead, then left and go down the ladder.
