If you took good care of your tama, then it's more than likely that it's a good character. But if you took bad care, then it might be one of the less favorable characters. But whatever the character you get, you should enjoy it! All of them are cute, if you ask me. Hope I helped!
Although there are really no "good" characters or "bad" characters, Kuribotchi is not one of the low-maintenance tamagotchi characters. I have only had it twice. I think it is one of the cutest toddler characters on v2.
