well first of all, what version is your tama??
if it ver 5 then you can exit the game by pressing the last button. where as other versions you cant do that.
about the universal characters, which are mainly in ver 4 and 4.5. when your tama isnt in a certain type, such as smart or sparkle or kind ect.... it goes into universal.
but if you earn enough points then you can get into a certain type.!! :kusatchi:
hoped i helped!
