If you want a Kuchi/Kuchipa family (you can't get it on your next generation though), you will need to mate with any adult and hope that you get a boy.
Then, use only the third bonding item for training and get the bonding to 80% or higher before it's an adult. You should get Kuchipatchi.
Raise the bonding to 100% and then mate Kuchipatchi with a Yonepatchi to get the Kuchipa/Kuchi family.
A Smart Family isn't a really special family though you do get a different family bar. It consists of Papamametchi, Mamametchi and one or two "smart" children (Mimifuwatchi, Mausutchi, Sakuramotchi, Mamekatchi, Chamametchi, Mametchi etc.)
