Heh, I just downloaded TygerCub's "open mouth" morph for the Poser horse...and it works really well. There was just one thing I'd not considered...the horse, of course of course, has NO TEETH! So I remembered, that WAAAAAY back in the dim and misty days of old, Zygote gave away a free set of poseable "chattering joke teeth". So I look through all my old Poser stuff that I haven't used in forever, and lo and behold, I still had them. So, with parenting and a little adjustment of the XYZ scales, I managed to fit some perfectly comical "dentures" onto the Magic Pink Pony!
