Chocograph

Chocographs are rare stones in Final Fantasy IX that serve as 'treasure maps' that guides the player to treasure chests that can only be found by Chocobos. Chocographs are found by chocobos digging in a game called Chocobo Hot and Cold played in Chocobo's Forest, Chocobo's Lagoon, Chocobo's Air Garden and Chocobo's Paradise. There are 24 in total, and they appear randomly at dig sites. Treasure boxes found contain many rare items, and even transports Choco to Chocobo's Dream World, thus giving the Chocobo new abilities and a new color.
