Hello there. I noted you need help with your Tama-Go. If you look at a growth chart (just look up "Tamago growth chart" and go to images), you can see that Gozarutchi is the worst care male adult for the odd generations. I don't believe training will affect it MUCH, but Freindship will. Also, are your character's hearts all full? Do you clean up its mess straitaway? Do you heal it when it's sick right away? If you want Gozarutchi, ignore its attention calls, that is how you get care misses. Many care misses (7-10, I believe) will result in a Gozarutchi. If you use this method in an even generation (2, 4, 6, ect.), you will get Necktietchi. Hope this helped, and good luck!
Yeah I do clean its mess and the friendship bar is full. Everything is good. Its a teen already so ill get Kuromametchi instead ;D ill try to get him next time. Thx for the help!
