Rupee Ore

are minerals in SS undefined that may drop a Rupee when shot.

Location and Uses
Rupee Ores can be found along the walls of the Thrill Digger minigame cave in the Eldin Volcano. By shooting at them with either the Slingshot or the Bow, they will occasionally drop a Rupee that Link can pick up. There are three colors of Rupee Ore, with each color corresponding to the type of Rupee that can be dropped. Green Rupee Ores can drop Green Rupees, Blue Rupee Ores can drop Blue Rupees, and Black Rupee Ores can drop Rupoors.
