I want more!
Now you can go on with the main quest by going to the Romani Ranch or get new items: a bottle and a new sword.
If you want the sword, you will also get the bottle, but you will be required to possess the Adult Wallet, have 100 rupees and you will have to beat Rhork again. You can get these items later, but the mountain must be bathed in sunlight.
To get the bottle alone, go back to the Goron Village and get in the cave in the north part of the area (previously blocked). Talk to the big Goron who asks you to destroy the boulder that blocks the entrance to the Goron Racetrack. Then he will give you a Powder Keg. Grab it quickly, throw it over the slope and roll to grab it again and go on. Next, run back to Tingle's location, cross the next bridge, then turn right and follow the path up to a huge rock. Quickly place the Powder Key next to the rock and let it explode! From now on, these kegs will cost you 100 rupees but you won't have to carry them anymore. Now enter the Goron Racetrack and talk to the Goron baby to start the race. You need to reach the first place to win and be rewarded with the bottle filled with Gold Dust. After the race go back to the big Goron and talk to him so he decides to let you handle Powder Kegs on your own and gives you another one.
To get a more reliable sword (and the bottle), play the Song of Time (since you have to start on the first day), then use the Owl Statue to get to the Snowhead Temple and confront Goht once again. Then go back to the Mountain Smithy and speak with the blacksmith. He will offer you to sharpen your sword for 100 rupees. Accept his offer, let him keep your sword, then head back to the Goron Village and get in the cave in the north part of the area (previously blocked). Talk to the big Goron who asks you to destroy the boulder that blocks the entrance to the Goron Racetrack. Then he will give you a Powder Keg. Grab it quickly, throw it over the slope and roll to grab it again and go on. Next, run back to Tingle's location, cross the next bridge, then turn right and follow the path up to a huge rock. Quickly place the Powder Key next to the rock and let it explode! From now on, Kegs will cost 100 rupees each but you should not need to buy any other.
Afterward, get in and speak with the baby Goron to start the race. You will have to get the first place to be rewarded with the bottle containing the Gold Dust. After the race go back to the big Goron and talk to him so he decides to let you handle Powder Kegs on your own and gives you another one. Play the Song of Double Time to reach the second day (if needed) and go back to the blacksmith to receive the Razor Sword. Zubora says that this item can be used a 100 times before it loses its edge and returns to normal and he adds that if you give him some Gold Dust before the sword loses its edge, he will be able to forge the strongest of swords. Finally talk to him again and give him the Gold Dust. Then get out and play the Song of Double Time to reach the third day. Again enter he house, talk to him and this time you will get the Gilded Sword which cannot break and lose its edge!
