Gossip Stone

Gossip Stones are found in Ocarina of Time, Majora's Mask, and Phantom Hourglass. They also appear in The Wind Waker, although in a different form.

These odd devices do and say different things depending on the game on which they appear. Gossip Stones can tell time, reveal information that they've heard, give helpful hints, or even reveal the locations of treasure chests.

According to the Ocarina of Time's in-game description, the statue speaks to Link by piercing into his mind.

Ocarina of Time
Link can speak to the Gossip Stones while wearing the Mask of Truth. Gossip Stones say a variety of things. Some information is helpful, and other information is typical conversational dialog.

Majora's Mask
When the Gossip Stone is attacked by Link's sword, the screen will shake and the stone will make a high-pitched noise. It will then tell Link how many more hours remain until the Moon crashes into Termina. If Link speaks to the ones scattered all over Termina using the Mask of Truth, it will him give information regarding certain people or places.

The Wind Waker
Link is given the Pirate's Charm by Tetra in The Wind Waker, and he uses it to communicate with Tetra and The King of Red Lions. It fulfills a similar purpose to the role played by Navi in Ocarina of Time. It is revealed later on that the Pirate's Charm is actually an enhanced version of the Gossip Stone made by the King of Hyrule himself.

Phantom Hourglass
In Phantom Hourglass, some Gossip Stones speak to Link without any conditions needing to be met, revealing hints that could become helpful later on. Other Gossip Stones, specifically the ones in dungeons, reveal how many treasure chests are left to discover. For a price of 20 Rupees, the stones show where those treasure chests are located.

Spirit Tracks
Gossip Stones appear again in Spirit Tracks, but this time they seem to have a more feminine appearance. Normally they are unresponsive even when hit, but if the Song of Awakening is played nearby, they'll speak. Like in Phantom Hourglass, the Gossip Stones in dungeons reveal the amount of treasure chests on the floor they are currently in for a fee of 20 Rupees. Other Gossip Stones appear in several sanctuaries that reveal hints or other useful information. In Lost at Sea Station, there is a Gossip Stone that allows Link to enter the temple located in said station.

Trivia

 * If a bomb is placed next to a Gossip Stone in Ocarina of Time or Majora's Mask, it will begin a countdown while changing colors and will shoot off like a rocket. By hitting them with the sword before they take off, they will stay the color they were. They can also be smashed into the ground using the Megaton Hammer or by pounding it as Goron Link. By using Din's Fire on one, the Stone will spin around and inexplicably stretch to double its height, soon snapping back to normal.
