You could also consider moding the nose to have it snort or breath. Anything to indicate it is a living thing and not a puppet head.

It already breaths. you can clearly see the Taun Tauns breath coming from its mouth in the movie. It wouldn't breath from its nose while its mouth is open

All you have to do is watch the link above and compare the time markers I listed. The movements are noticeably different.

I already have done that before i replied to you last time. the ear wobble is not due to movement. The ears have a skeletal like rod in the upper part of the ear extending from the skull to the tip of the ear. This creates the movement and also the vibrating wobble. The ears aren't just rubber like most puppets are. if you look at the shot where he turns around at the beginning of the clip you can see that the ear vibrates. if it was a wobble due to the rubber it would have not have continued the vibrating motion for so long after the puppet turned.
