Me too. That's one of the reasons I've been scouring the net for Horo pics. I'm almost desperate enough to order the light novels, but my Japanese book pile is just a little bit too big right now.
Not at all sure. In this case, my curiosity is part of my fascination.
That said, if the manga is any indication, Horo is a mischievous ball of fun. Between that, the ears, and shameless nudity, you get instant sex-appeal.
