the ear wobbling was done deliberately at the time of filming as it had a mechanism built into the puppet to make the ears do that so it doesn't need to be changed. I'm keeping an eye on the hands but there isn't much i can do about those.

I am referring to the ears wobbling due to the bouncing of the Yoda puppet as it is being moved. Again, per my previous post, it is a different movement from the deliberate movement as listed when the FX operators are having Yoda's ears move to show emotion (like when they perk up or level out due to what Yoda is saying). Note that when Yoda's ears move deliberatley due to emotion the movement is smooth, as opposed to the rubber ear wobble which is fast and not reactive to what is happening on screen other than the movement of the puppet itself. Also note that the mechanism in the ears was within the base of the ears, not the tips; it is the Ear Tips that waggle when he moves, not the base, which moves the entire ears (from 50 to 100%) to express emotion.

Even, then, it is not natural that a living thing has wobbly ears, being that I do not know any human or mammal whose ears wobble when they move.

The ear wobble is something that has affected most if not all puppets and animatronic figures throughout the 80's simply due to the ears or other small or thin parts not having the same structure or rigidity as flesh-and-blood ears, thus when said creature moves the momentum causes vibrations and thus movements in the neck and ears.

All you have to do is watch the link above and compare the time markers I listed. The movements are noticeably different. In fact, compare 0:12 to 0:22 to 0:24. When Yoda first turns around the ears are wobbling at the tips. In the second time marker, the ears are more stable at the ends.
