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 and beams into the sky. When Link goes back to the sky on his Loftbird, he can fly to various islands and find mysterious purple chests; their locations correspond to the locations of the cubes on the surface and each chest appears when its Goddess Cube is struck.
