I booted up 2 of my tama mix after a long time not playing, they’re in teen stage at the moment and I was wondering if it was possible for them to grow into Wagassiertchi and Kikitchi? Or are they only characters you can marry?
I think it is not possible to raise Wagassiertchi and Kikitchi because they are not base/built-in characters. You will only be able to marry them to get their traits.
That said, if you Mix with them enough you'll eventually end up with all of their traits.
See: my Masktchi on the 20th Anniversary Gift version https://mix.tamatv.com/family_trees/user_family_tree/26093He's got hidden Mametchi, Mimitchi, and Kuchipatchi genes, but you can't tell by looking at him!
