This is Gary the Chocobo. He has a total of six sates that he can be in (Sad, Happy, Green, Blue, Black, and Gold). If you can turn Gary Gold then you have achieved his goal or terminal state. To do this you must feed Gary the correct food items to get him to progress to a higher state. (Hint: If you are at the black state and you correctly feed Gary then you have a slim chance of achieving Gold status, otherwise Gary will turn sad and you must start from the beginning). Good Luck
