Rupoor

A Rupoor is a black Rupee-like item that appears in The Legend of Zelda: Phantom Hourglass. It is first encountered on the Ghost Ship, after one of the Cubus Sisters advises Link to gather treasure from one of two chests. Opening the chest that the Cubus sister recommends results in Link finding a black Rupee, or the Rupoor.

Finding a Rupoor will cause Link to loose ten Rupees.
