Gossip Stone

Gossip Stones are found in Ocarina of Time, Majora's Mask, and Phantom Hourglass. These odd little devices do many a senseless thing. When you slash one with your sword it will tell you what time it is, or how much time you have left (that is, if you are playing ''Majora's Mask). If you place a bomb next to one it will shoot off like a rocket. You can also change the color of the stone this way, when the bomb changes to either blue or red, hit it with your sword. You can smash them into the ground using your Megaton Hammer. And after putting on the Mask of Truth, you will find out why they are called Gossip Stones. In Phantom Hourglass, they will talk to you without any conditions needing to be met. They might unlock certain challenges.
