On the 3rd floor in Goron City, there is a doorway that leads to a Biggoron’s shop; use either bombs or bomb-flowers to take out a series of barriers to reach the shop.
You can purchase the Biggoron’s Sword from the Biggoron for 200 rupees. After a while though, the sword will break due to excessive use. However, there is a way to get a Biggoron Sword that won’t break no matter how many times you use it. Below is the entire process, or trading sequence, to obtaining the Biggoron’s Sword.
Who & What You’ll Need
Epona is a horse that resides within the Lon Lon Ranch near the middle of the Hyrule map. In order to have the ability to ride Epona whenever you’d like, you must first win her in two races against Ingo. The first thing you need to do is march on over to Lon Lon Ranch and speak with Ingo. He will then prompt you to pay ten rupees in order to jump a few fences with one of his prized horses. Upon doing so, you’ll be moved into the center of the corral. Ingo will then offer you a horse – however, this is not the horse you should pick. You need to get out your ocarina and play Epona’s Song to call Epona over and use her to jump the fences. (Remember to press A just before reaching one of the fences if you’re having troubles with jumping).
Once you’ve finished with the jumping exercise, ride over to Ingo with Epona and speak to him. Make sure you’re using Epona, because you’re bound to lose the race with the other horse. Now, accept the challenge that Ingo presents you and you’ll be transported to the starting line on the race track.
This is the beginning of the first race. Unfortunately, Ingo will give himself a head start to the race, but don’t fret! Ingo takes some pretty large turns around the corners, leaving you with a wide open opportunity to sneak past him at every turn. With this in mind, you should also take advantage of those little carrots up on the top of the screen. These carrots are actually bursts of speed that aid you in winning this race (use by pressing A). There’s just one thing you need to keep in mind when using these carrots – use them sparingly! If you happen to use all of the carrots at once, Epona will slow down to an alarming rate, which will basically ruin your chances of winning. Now, with all this in mind, feel free to proceed with the race. Remember to stay near the inside of the track so you’ll have an easier time getting around Ingo. If all goes well, you’ll win the first race and move onward to the second and most important race.
In the second and final race, Ingo slightly steps up his game by attempting to block you off whenever you get close enough to bypass him. However, the same rules apply as above – use your carrots every time they recharge and stay near the inner circle to improve your chances of getting around Ingo.
Once you’ve won both races, Ingo will lock the entrance gates so that you’re trapped inside the ranch. All you’ve got to do now is use Epona to head for either the fence or those short walls while using your bursts of speed and you’ll be free!
For this song, you’re going to need to be playing as Young Link. Head on over to the graveyard (located in Kakariko Village) and look for the large gravestone near the back. If it has a triforce symbol, then you’ve found the right one. Simply stand in front of it and play Zelda’s Lullaby, which will cause the gravestone to be destroyed, leaving a nicely sized hole for you to squeeze into.
Inside, you’ll find three chambers awaiting your arrival. Upon entering the first, simply kill any Keese you may see. You’ll then need to proceed into the second chamber, where a number of Redead are waiting for you. These guys might be a bit intimidating at first, but with a bit of luck you’ll be able to find a path through to the next area. After you’ve gotten past the Redead, you’ll journey into the final chamber, where you’ll find some nice instructions on how to play the Sun’s Song.
The Trading Sequence
1. Pocket Egg
To begin, go to Kakariko Village and talk to the girl who raises Cuccos. She will give you an egg containing a Pocket Cucco to incubate. On the next day when the egg hatches, take the newborn Cucco to Talon (who is slumbering away in the house to the right of the potion shop) and use the Cucco to wake him up. Go back to the girl and give her the happy Cucco. In exchange she will give you Cojiro, a blue Cucco that for some reason rarely crows at all.
Now that you have Cojiro, make your way to the Lost Woods. Upon entering, take the left tunnel to find the girl’s brother sitting on an old tree stump who appears to be suffering exhaustion. Show him Cojiro, and he will ask that you take an Odd Mushroom to his grandmother back in Kakiriko.
3. Odd Mushrom
Keep in mind that you have a limited time to get this Odd Mushroom to the old woman. She is in the hidden potion shop that is behind the potion shop across from the Bazaar. Deliver the mushroom before time runs out, and the old woman will give you the Odd Potion to take back to her grandson (the guy on the stump).
4. Odd Potion
Upon receiving the Odd Potion, go back to the Lost Woods where you first met the girl’s brother. In his place sits a Kokiri girl. Hand over the potion to the girl and in exchange, you will get the Poacher’s Saw.
5. The Poacher’s Saw
Take this saw to the Carpenter that is standing just outside of his tent in Gerudo Valley. In exchange for the Poacher’s Saw he will give to you a Broken Goron’s Sword.
6. The Broken Goron’s Sword
Make your way to the summit of Death Mountain to see Biggoron. He will tell you that he would be more than happy to repair the sword. Before he can get to work, however, he needs Eye Drops from King Zora, so he gives you a prescription to take to the king who resides in Zora’s Domain.
7. The Eye Drop Prescription
Go to Zora’s Domain and show King Zora the prescription from Biggoron. King Zora will tell you that he has no eye drops available. So instead he offers an Eyeball Frog, which is a chief ingredient in the Eye Drops. King Zora will also suggest to you to take the Eyeball Frog to the professor who lives next to Lake Hylia.
8. The Eyeball Frog
You have three minutes on the clock, so you can’t travel by foot because time will run out. And if you warp, the clock will go straight to zero. So ride Epona to Lake Hylia, enter the Lakeside Laboratory and give the Eyeball Frog to the professor. He will then make the Eye Drops that Biggoron so desperately needs to repair your sword and will give the Eye Drops to you.
9. Eye Drops
Four minutes are on the clock this time, so make your way quickly back up to the Death Mountain Summit before the Eye Drops spoil, and give them to Biggoron so that he can get to work on the long-awaited project. He will give you a Claim Check for the sword and tell you to come back in a few days.
10. Claim Check
Have any unfinished business to attend to? If so, get all of that taken care of now. When three days have passed, go back to Biggoron and give him the Claim Check to get your Biggoron’s Sword.
11. The Biggoron’s Sword
The Biggoron’s sword is twice as long and twice as powerful as the Master Sword. In fact, it is so long that you need two hands to use it, so you can’t use a shield with the Biggoron’s Sword equipped. Furthermore, you cannot use the Biggoron’s Sword to smite Ganondorf, because this sword is NOT the Blade of Evil’s Bane. Only the Master Sword can defeat Ganondorf.
