Ponda Baba is the person whose arm got sliced off by Ben kenobi in the Cantina.
Like I've said, this has nothing to do with the bleeding arm business. I think no one had mentioned this before, so, I'll just post. Aqualish are supposed to have 4 eyes/two pairs of eyes, am I right? Many pictures showed this very thing. But Ponda Baba had only TWO! How can he have two eyes? His homeworld's the same as everyone's (Ando... in the Expanded Universe section of the databank.), so, he couldn't be a different species, judging from the many Aqualish seen on screen and in the Visual Dictionary. But of course, this very fact would prove useful for those saying the Doctor did it to him because Ponda didn't like that extra pair. But the Doctor's a little insane... he like carving flesh. Ponda wouldn't look like that anymore...
Speaking of Visual Dictionary, the dictionarty seem to have mistakenly pointed out that the extra pair of eyes is due to MUTATION. This is clearly wrong, since the Aqualish Senator had two pairs of eyes as well.
i never made any thoughts about ponda baba...i think its because i where always afraid of him when i first whatched ep 4 when i was six....
well, if you saw his friend the "I don't like you" guy he was all mutated so maybe Ponda was mutated also
now..I could start about the bleeding arm and I'm sure other people will aruge...but I think I like not being banned for treason(why'd I say treason? I dunno!)
edit> well now I read the rest of your post and you crushed my dreams or mutaions, maybe there's another species on the planet and it's like different color eyes or hair color, height even.
Or maybe it's evolution and they got four eyes to see better, or lost the extra eyes because they did nothing
