I guess we might find out why Myxo was considered an outsider or outcast. She seems like a very nice person/bunny so I'm curious why her peers would reject her like that. Enough for her to move to a new town as well.

It was always a plot point I wanted to develop. In the original comic her box house is away from the residential area and up until the events in Dice she was pretty much shunned and invisible. But it never really got explored as I was just writing whatever I felt like at the time and dropping unfinished plot lines all over the place. It may still be a sub-plot related to the city and not something that affects her in Bunton directly (but indirectly, psychologically, it might). We'll see. There is also a physical difference that Jane and Myxo share that other bunnies do not, and I might use that (it was a deliberate difference).

Is the physical difference they share the fact that their ears always seem to be down?

I always liked that feature btw. Even in her early design when her ears were a lot bigger and floppier.

Yes. The lop ears was always intended to be just for Jane and Myxo.
The big ears were fun, but they interfered with rear views and just got unmanageable.
