I just wish I could see some x-rays. Anyway, I've always wondered why the gungans allow themselves to be ruled by a giant frog. After examing the movie, the 3 3/4" and 12" figures of Nass, I have to conclude that he is not a gungan. It's possible that he is half gungan and half. . . I don't know maybe Hutt or something, but there's no way he is the same species as the gungans.
Okay, we see hundreds, maybe thousands of gungans in TPM. From looking at the films and figures, it seems their average height is about 6'5" or 6'6"; Nass is shorter that Obi-Wan. Wouldn't that make him about 5'8" or 5'9"? Also, all of the zillions of gungans we see are some shade of pink, orange, or purple; Nass is the only green alien living amongst them.
Finally, and this is where x-rays would be useful, just by looking at his head and body, I don't see how the skeleton could be identified as the same species with the rest of the gungans. First of all, his eyes are on the front of his face and more sunken in while all gungans' eyes are on top of there heads and protrude on stalks. Also, the slope of Nass's bill is almost vertical and fairly broad while all the rest of the gungans have very prominent narrow bills that are at almost a 90 degree angle from their face. From that there is no way Nass's skull would be considered the same species.
Does anyone else see my point? I know this is irrelevant to the movie, but it just is very distracting to me.
