Well how to not get masktchi and gozatchi, u have 2 take good care of ur tama.
Like, try keeping all the hearts up as possible. Well basicly, treat it like its ur best friend, not a baby. It will feel as if it can always get attention. Like, if the attention icon comes up and nothing is wrong with it, punish it.
Yeah, you usually get Gozarutchi and Maskutchi when you take fairly bad care of your Tama. So just try to be more attentive, and you should steer clear of those characters Good luck!
