Rock Sirloin

Rock Sirloin is a premium type of rock that Gorons love to eat. It is mentioned in both Ocarina of Time and Majora's Mask, but can only be acquired in Majora's Mask. Even so, it is not picked up and added as a C-item, but must be carried to its ultimate destination of the Mountain Village, where a weak, hungry Goron will eat it and reward Link with Don Gero's Mask.

Gourmet top sirloin rocks can only be found in the Dodongo's Cavern, the quarry of the Gorons. They're so delicious, in fact, that when the Gorons are cut off from their supply they can't stomach rocks from anywhere else. Interestingly, the Terminan Rock Sirloin also comes from Dodongo's Cavern, though exactly how that is possible is something of a mystery; however, the Goron that reveals this calls it "Dodongo Cavern" instead of "Dodongo's Cavern."
