I'm almost sure that you probably have seen this already, but I'm going to post it just in case...
http://tama-zone.com/index.php?showtopic=15082&view=getnewpostIt's the chart from tamazone..it's pretty accurate, except for the part where it says that the bigger one is most likely..what does that mean? If you take better care of your tamagotchi you'll get the bigger character or is it just chance?
