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.
Thereis no Goron City in Majoras Mask. But there is a Goron Village in the Northern Mountains, but before you can go there you need to get the Hero's Bow from Woodfall temple.
There's only one way to get past Biggoron: slip into the Goron Mask and play the Goron Lullaby. Biggoron will fall asleep and fall over, effectively clearing the path to the Snowhead Temple.
To get gold dust you must first acquire the keg bomb from the Goron Elder in the Goron village. Then take that to the goron raceway and destroy the rock. Go inside and talk to the littlest goron and he'll ask you if your going to race. Say yes and start racing. If you finish first you will receive gold dust. If you take it to the swordsman he'll make your sword stronger.
To get the mask, Get the lens of truth, Look at the shadow (in goron village), Follow the goron, then play the song of healing! Hope I helped! =D
there is no goron armor in the game only zora and magical
If you stop the rolling Goron in Goron City, he will tell you his father is Darunia and that he went to the Fire Temple; he will give you the Goron Tunic if you talk to him enough.
You can see various things normally you wouldn't see like the goron ghost or platforms.
Shoot him with a fire arrow then transform into Goron Link. Spike roll into him until he falls. Keep spike rolling into him as much as you can. When he gets up he's going to kick rocks, throw bombs and lightning bolts at you. Just keep hitting him with the spike rolls, collect magic from the pots and he'll evetually run into the wall and be crushed. You win.
You Need To Blow Up The Entrance To The Goron Racetrack On The Ledge You Need To Roll Up As A Goron.
At the Goron island dungeon
Gorons, can't jump very well, but they can pound. Press a and hold, which should put you in ur roll form, the press b to pound. I can't tell for sure, but I bet ur at the part where ur trying to get into the goron's frosty shelter, aren't you? :)
He's frozen in the area just before you enter the village, where there are a bunch of chunks of land separated by ice.
