Chocobos can be caught and sent to the Calm Lands Ruins after the player has cleared the ranch of fiends and obtained some greens from Clasko . Chocobos will occasionally be encountered in battles even before that , but will always run away . To catch a chocobo they must be faced in the field alongside fiends in random encounters . Although they are more inclined to run than to stay and fight , chocobos can fend for themselves when pushed . Chocobos can heal themselves with Choco Cure and cast supportive magic , as well as attack with Choco Kick and Choco Meteor . Chocobos are immune to Gravity as well as to most status changing spells . They are resistant to Eject , Zantetsu , and , at higher level s , Confuse . To capture a chocobo , the catcher must entice it to stay by offering it Gysahl Greens and maintain a steady supply of the greens while clearing away the accompanying fiends . When the fiends have been defeated one more Gysahl Green should be enough to ensure capture . During the battle the chocobo may attack ; it is important the catcher does not retaliate , or the chocobo will almost certainly run away . Calm Lands Ruins . Created and run by Clasko during the Eternal Calm , the Calm Lands Ruins used to be a fiend hunter - styled zoo , called the Monster Arena , that had fallen into disrepair . Upon discovery the ruins had to be cleaned out of fiends if any chocobo were to be safely raised inside . The Gullwings assisted greatly in the production of the ranch , first being instrumental in the " cleaning out " of the facilities and secondly allowing any chocobo that they caught to be raised at the ruins . The Amazing Chocobo . First discovered beneath the Calm Lands Ruins , the Amazing Chocobo was guarded by an Anything Eater before being freed by the Gullwings . The Amazing Chocobo is bright gold and capable of flight . It also demonstrates a great degree of intelligence and initiative in comparison to other common chocobos . Raising chocobos . The main facility provides accommodation for a total of 14 chocobos . The chocobos are raised with a diet of nutrient greens such as Pahsana , Mimett , and Sylkis , as well as the use of Gysahl Greens as a candy - like treat . The chocobos are eventually trained as dispatch go - fores as they are instructed to explore certain areas of Spira and return with items and treasures . Thus is how the ranch provides its income . Music Themes . In " Final Fantasy X " , " Brass de Chocobo " ( also known as " Chocobo Jam " ) is played when riding a chocobo on the Mi ' ihen Highroad . " Final Fantasy X - 2 " has another chocobo theme , simply called " Chocobo " .
