Bad parenting

How does a Young Mimitchi end up being a Memetchi adult? I'm so disappointed!

My Tarakotchi Colin and Mametchi Marie had twin daughters who were both Kinakomatchi, then one became an Ichigotchi and the other a Young Mimitchi. I thought I had a good chance at getting another Mimitchi but no, it became a big-headed sparkly-eyed Memetchi! Gaaaah.

Maybe I should feed them less, I keep offering them food all the time. Let's see if Mametchi Melia can raise a Mimitchi child. I bet Memetchi Delia will make a lousy match and raise some weird-ass character. *frowns at Delia*
