You say that like it’s hard to begin with. I do it all the time when I breed pokemon. Also, might want to include some non-anthro mons in your examples.
I know basically nothing of pokemon past gen iv. But from what the Galgarian forms look like, I’ll go with emo. I like to think of the bird pokemon going through emo phases. To the disapproval of their parents.
Penny (The Rescuers) and Cody (The Rescuers Down Under). Maybe Penny would visit Australia with her parents, and she would meet Cody, and both of them realize that they’d been rescued by the same two mice.
