The first chao I ever had turned into a hero and it's been one ever since then. I went to the docter and it says it's still only 2 years old when I've spent it seems like forever with it? How long will it take to get it to be 4 or 5 years old? ( the time when it evolves or reincarnates or w/e you want to call it.) If anyone could help me out I would appreiciate it.
