How found: Use the Lens of Truth and the east end of Goron Village to find the ghost of Darmani the Third. Talk to him and follow him all the way back to the Mountain Village. Switch to Deku Link and hop across the frozen pond, then reveal the ladder with the Lens of Truth and ascend the cliff. Go right, left, and right at the intersections to reach the top, then enter the cave and speak with Darmani's ghost. Play the Song of Healing to put his ghost to rest; he'll turn into the Goron Mask.

    How used: Puts Link into the body of a Goron, allowing him to smash rocks with his fist, pound the ground, and roll up hills.
