Chocographs
While playing the Chocobo Hot & Cold game, you will find Chocographs hidden beneath the soil. These chocographs are maps to locations on the world map. While riding a Chocobo, you can look for this treasure on the map. Just go to a location where you see the Chocobo footprints on the ground and use Gyshal Greens to call Choco.
You will also notice Chocograph Pieces. Find them all to form another, important Chocograph
Some chocographs are not accessible until you find some chocobo abilities. For the location of Chocographs, see the Chocobo Map.
