One weird thing I notice with the milenium teeth--when the morph on the face matches up to the the "open" name, it sometimes cross-talks it into opening!  I do not remember whether it happens when parented, or conformed, but that it happened stuck in my mind, and might be worth pursuing an investigation?

A "Mouth Open" on the head would be best. It's like a horn being looked for on the steering wheel, not on the dashboard.  A dashboard might be closer to the horn, but most people won't look there.:laugh:
