I found the game after the first push Champaign ended. now my Felicia is forever lonley :c

I have beaten the entire game and al possible paths, but I'm missing Margaret's fourth transformation, the one between her fully mouse-ified and the one where she's in her bunched-up sweater. Anyone know what that is and how to unlock it?

So, I haven't played through all of it yet (only done one big playthrough actually xP ) so, I was wondering exactly Where the new character can be found? I don't want to know any details or anything like that, I'm just curious about what's new, so I know when I find them. So... what story line shows the new character? :3...

I recognize a She-Ra, She Hulk (maybe), Miku (maybe), Studio Ghibli (very not confident), and RWBY (even less confident). I know there's also a Switch and a PS4.

Can I just say that, while Sylvia's route was my personal favorite, I was a bit disappointed by one detail. That route ends (in the true plot) post-marriage. I, personally, would have loved to see that ceremony between the two of them. Even if we didn't see the whole event, a picture of them in their wedding dresses would have been great....
