Powder Keg

The Powder Keg is an item in Majora's Mask that can only be used while wearing the Goron Mask. Its uses are to explode giant rocks that appear rarely. One of such is blocking the entrance to Romani Ranch, another blocking light from going through the ceiling of Ikana Castle (not actually a rock, just a cracked ceiling), the other one being in Snowpeak, blocking the path into the Goron Race Tracks. You are only aloud to carry one powder keg. The Powder keg is pretty much exactly what it sounds like, a big keg of powder or a big bomb. It has a long fuse and can only be used once you pass the gorons test.
