Goddess Cube

Goddess Cubes are mysterious cubes that are scattered all over Hyrule in Skyward Sword. In Faron Woods, a Goron traveller, Gorko, tells Link about these cubes and that the Skyward Strike has an effect on them. When Link uses the strike on the cube, it disappears from the surface world while sending a beam into the sky. These beams activate special "Goddess Chests" scattered throughout the sky, which contain treasures that are rare and more valuable than those in mundane chests.
