Thats what mines been doing alot latly they will have full training i dont feed them candy unless i REALLY have to (like if they wont play a game, and i cant feed them anymore meals) and i got a masktchi i dont understand it.
On my next generation (7) my gozaruchi will leave and I'll try all the "good care" things (punish/praise,full training,hardly ever feed it snacks unless i'm really need too).
I'll post and see what I get. OR it might be because i'm connecting with a lot of masktchis (I have) I'll try harder.
what are it's hearts like when it evolves? if they're down 3 hearts on each one i think that's why. oh and you have to take REALLY good care of the children and babys other wise:
the babys grow into a kinokamatchi
the kinokamatchi evolves into either an oinionotchi or a hinotamatchi (they're the worst teens you can get!)
The main reason oyu might be getting them ones, id bacause of the amount of snacks. Play wioth it all the time when its un happy, unless you are busy (school, word meeting etc...). Good luck!!
