Sounds like you have a V5 Familitchi.
Well, to get the Easygoing Family, first of all, you need a Kutchipatchi, as you want, lol.
To get Kutchipatchi, you'll have to have your tama's bonding level to 80%
(least) before it evolves into an adult (
growth chart) . You MUST select
ONLY the third icon when your pet calls for training (which occurs at 10am, 12pm, 2pm, 4pm and 6pm). If you choose another icon once or twice, I doubt that it will effect the easygoing family, however, just to be safe use only the third one. If you think the bonding level is raising to slowly, use the items to help raise it. ( Everything about bonding can be found
HERE )
Finally, to get the Easygoing Family, you must marry your Kutchipatchi to Yonepatchi. (this can't be done the other way around)
NOTE: Your Kutchipatchi
MUST be
100% bonded!
