The Graceful Gorons are characters in Oracle of Ages.
The Graceful Gorons are part of a significant lineage, having a variation of unusual skincolors, as the usual skincolor is brown/gold. They reside in the Rolling Ridge and are found in the Goron Dance Hall. When Link enters the Dance Hall, they give Link instructions on how to dance. If Link matches their moves, he will be rewarded with a prize. Link can acquire the Brother Emblem in either the Past or Present.
In the Past, the Graceful Goron is red and the first generation of Graceful Gorons. If Link dances with him at least well, he will be rewarded with the Mermaid Key and the Brother Emblem. If Link gets a perfect score through a Linked Game, he will be rewarded with the Bomber's Ring.
In the Present, the Graceful Goron is blue and the fifth generation of Graceful Gorons. If Link dances with him at least well, he will be rewarded with the Brother Emblem. The Brother Emblem can be shown to the Goron near the Dance Hall to gain access to new areas. He is the first and only blue Goron to ever exist.
