Rupee Rocks can be found all over Hyrule. If Link hits them with his Sword, Rupees will pop out for a limited time every time it is struck. If the Rock is hit enough times, higher values of Rupees will start to appear. They will also drop Rupees if a falling Boulder lands on them. If Link lifts one, they will turn into normal Rocks.
