I don't know which version you're talking about, but oh well.
V3- Oyatchi [get him by mating Otokitchi w/ the other old dude]
V4- Makiko, Nonbirtchi, Tensaitchi [get them by getting Kuchipatchi, Mametchi, or Memetchi w/350 skill points and having 450 in total
Flower+kuchipatchi= Nonbirtchi, Pencil+Mametchi= Tensaitchi, and Star+Memetchi= Makiko.]
V4.5-Same thing w/ V4's but this time There's Hangatchi, Mukimukitchi,
and Hyokkotchi [ Uramemetchi+star= Hangatchi, Urakuchipatchi+BottomFace=
Mukimukitchi, and Uramametchi+Top Smileface= Hyokkotchi]
V5-There's Kuromametchi, Makiko, Papakurotchi, and Majorite.
[get Kuromametchi by Getting hatugatchi and feeding it Sesame Pudding, Get Makiko by Getting watatchi and using girl's dresser and get papakurotchi and majorite by evolving the two others into parents.]
[You can get Oyatchi in any other version exept v5.]
Hope I helped!
