im character-choosing discoverer! i know how to easily get kuchipatchi and ANY other character. simple!
1. reset it/kill it/make it marry.
2. name the new baby ODD GEN BOY Kuchipa.
3. take OK care of it (u surely know how to do that).
4.wait until its an adult and taah daah! kuchipatchi!
5. if u don't wanna senior (ojitchi) then keep it paused most of the day.
6. stays kuchi for as long as u like!
hope it helps!
