The gold chocobo, known as the Ocean Chocobo, is the final result of the chocobo breeding sidequest, resulting from breeding a black chocobo with a "wonderful" yellow chocobo using a Zeio Nut. Additionally, once the player has at least two gold chocobos of opposite genders, it is possible to breed these, or their offspring after sufficient time, to produce additional gold chocobos. The gold chocobo can cross all types of terrain and so can reach the Round Island where the Knights of the Round Materia is found. When racing in the Gold Saucer Chocobo Square, gold chocobos have the highest stats of all types, and are unaffected by all course hazards.
Aside from breeding, the player can acquire a gold chocobo by defeating Ruby Weapon and giving the item it drops, the Desert Rose, to the Kalm traveler. However, a gold chocobo obtained this way has poor stats compared to gold chocobos bred by the player.
The gold chocobo is called the Sky Chocobo, and is Choco's final evolution. The player must locate the six Chocograph pieces in Chocobo's Forest and Chocobo's Lagoon, completing the Mist Ocean chocograph that holds the Sky upgrade. The gold chocobo can enter Chocobo's Air Garden. The golden Choco can fly across the sky and land in any forest, homage to how flying chocobos worked in Final Fantasy V. This enables it to access remote islands that do not have a coastline, as well as the Forgotten Continent. Choco may also enter a new location known as Chocobo's Air Garden, where the game's most challenging superboss, Ozma, awaits.
It was long rumored that some versions of Final Fantasy IX have a "Gold Chocobo bug", in which the player could obtain the gold chocobo before they obtain an airship, allowing some parts of the story to be skipped completely. However, it has since been determined to be a hoax.
The player can open a hidden container to find a Golden Chocobo in A Dying World 700 AF. It is among the top Commando type Paradigm Pack monsters and one the best contenders in the Serendipity chocobo races. It doesn't stand out as much as in other games though, as it is overshadowed in racing by the Silver Chocobo and matched by the Red Chocobo as a Commando, though with different specialties. Golden Chocobo is one-of-a-kind monster.
The golden chocobo usually appears in select events alongside several red chocobos. They usually yield rare abilities or summons that pertain to the event. In order to obtain these abilities or summons, one would have to feed all of the red chocobos Vomp Carrots prior to finally feeding the gold chocobo itself its own Vomp Carrot. In rare instances, simply feeding it Gysahl Greens may result in a rare ability or summon.
