How do you find him?
Start at the mout of the cave to Dondongo's Cavern (this might be covered with a rock if you have not opened it yet). Start walking up the path. Walk for a little way, and then stand still. A goron rolling down the hill carrying a bomb will surely run into you, knocking you over and ridding you of some of your hearts.
Goron City is on top of Death Mountain.
Inside death mountain crater. u can enter from goron city after you have the goron tunic go behind the statue in darunia's main room
You get it by giving biggoron the broken goron's sword.
If you meant "How do you get the Goron Bracelet inthe legend of Zelda: Ocarina of time", then you must play Zelda's Lullaby and Saria's Song for Darunia, the Goron leader. Make sure you play Zelda's Lullaby first.
There are two main ways of obtaining this tunic. One is to stop the small Goron rolling around Goron City with a bomb when Link is an adult, and the other is to purchase it for 200 rupees from the Goron Shop. If you purchase it from the shop first, the rolling Goron won't even mention anything about a tunic. Hope that helps Remember to have fun and enjoy :)
There is a small Goron in Goron city if you bomb him he will give you the Goron tunic and open in entrance to the fire temple
Keep going up Death Mountain until you get to a red flag then follow that path until you see a big open door so go in there
In The Legend of Zelda: Ocarina of Time for Nintendo 64, the Sage of Fire is the Goron leader, Darunia.
Goron Mountian, named Death Mountain in this game, is at the upper left corner of Kakiriko Village.
To get the Goron Tunic in Ocarina of Time, return to Goron City as an adult after beating the Forest Temple. Go down to the 2nd floor (I think) and bomb the small goron rolling around. He's kind of hard to get, but when you do get him, he sits on the ground and starts whinng. Talk to him and after a long and boring conversation about the Fire Temple and Volvagia, he'll tell you how to get into the Fire Temple and will give you the Goron Tunic. Another way is to get the largest wallet and buy it from the general store, but I don't think that's possible at that point in the game unless you use a cheat.
If you're referring to the Rolling Ability of a Goron then it allows you to Go fast, and destroy many objects you couldn't normally destroy with your Spikes(Rolling), also you can use it to defeat the Boss Goht.
use the song you learn from saria inside the lost woods on the goron chief after playing the song the chief goron dances to the music
