Things You'll Need
Instructions
Play through the majority of the game until the party acquires the airship called the Highwind and the city of Mideel is attacked by the creature known as "Ultimate Weapon."
Go to the chocobo stables and rent as many stables as you can from Choco Bill.
Buy several "Reagan" or "Curiel" greens. The Reagan greens are better, but cost much more and can only be purchased from the Chocobo Sage at the far north end of the world map.
Equip the "Chocobo Lure" materia on any of your party members and find the chocobo tracks on the ground near Gold Saucer.
Fight in random battles while walking on the chocobo tracks until you are attacked by a chocobo accompanied by two creatures called "Spencers."
Use the Reagan or Curiel greens on the chocobo and kill the two Spencers. Once they are dead, you will capture the chocobo. Send the chocobo back to the stables, then come back to this spot and catch another one of these chocobos.
Travel to the city of Mideel and fight random battles while walking on the nearby chocobo tracks, until you are attacked by a chocobo with two creatures called "Spirals." Use the greens on the chocobo and kill the Spirals, then take the chocobo back to the stables. Return to this area and catch a second chocobo.
Purchase two "Carob" nuts from Choco Bill and use them to breed your two sets of chocobo, which should produce a green chocobo and a blue chocobo.
Breed the blue chocobo with the green chocobo using another Carob nut to produce a black chocobo.
Fly in the airship to the Icicle Inn at the northern end of the map. Fight in battles on the chocobo tracks here until you are attacked by a chocobo with two creatures called "Jumpings." Use the greens on the chocobo, kill the jumpings, then send the chocobo back to the stables.
Travel to the place called "Goblin Island," which can be found to the north and east of the chocobo stables. Fight in random battles until you are attacked by a goblin, then use the "Steal" materia on the goblin to acquire a "Zeio" nut.
Breed the chocobo you found near Icicle Inn with the black chocobo, using the Zeio nut to produce a gold chocobo.
Ride the gold chocobo over the oceans and mountains of the world until you find a small island at the top right corner of the map that is inaccessible with either the airship or the submarine. On the island, you will find the "Knights of the Round" materia.
