Leveling up. As days (in real life) pass, your Chao level up. Then, based on allignment, levels, and stats, they change forms. Well, they unlock them. Then you can pick and choose as long as their still on the current allignment. So if you unlocked Sonic and you're on the dark side, you can't use him until you switch over to the light side. However, you can pick between other characters on the dark side while you're there.
