IIRC, the arm you see draw the blaster up at Obi-Wan is Evazan's right arm and not Ponda Baba's. The furry hand on the ground (added later in some pickup shot) is the right arm of Ponda Baba, but again this is in conflict with the on-set flipper hands of Walrusman and the fact that he lost his left arm in the behind-the-scene photos.
So, what you're saying is that...
- if I display Ponda with the "flipper hands", then I need to display him with both arms attached to be movie accurate
- if I display Ponda with the "furry hands", then I need to display him with the bloody stump to be consistent with the pick-up shot
- if I display Ponda with the "flipper hands" and the bloody stump, I'll be violating the original continuity intent of the scene (before the pick-up shot ruined that) and the universe will implode
I look forward to seeing "Ponda Baba with bigger head and correct original continuity left arm bloody stump" show up in future JD wishlists and the inevitable "Ponda Lost his Left Arm!" T-Shirts at future conventions...
