Keeping these Snivvians straight seems like a full time job!
I went back to watch the Cantina scene from the Holiday special based on what Muftak said. And Bea Arthur does call that particular Snivvian Zutton. I had seen someone elsewhere identify that Snivvian as Zutmore. And then there's Takeel!
Looking through some screencaps of the Cantina scene in ANH it looks like there could be more than one Snivvian in the Cantina. One of the clearest shots I found in checking out some screencaps is a Snivvian facing camera when Wuher is telling Luke that the droids have to leave. And there's also a shot of a Snivvian sitting by Han & Chewbacca's booth when the Sandtroopers go to check things out. Both of them look like they're hunchbacks, but the first one seems to have thicker hair than the other. And Wookieepedia identifies a Snivvian seen on the streets of Mos Eisley (after Luke sells his speeder) as Zutton, the one sitting near Han & Chewie's booth as Takeel. And the Snivvian who was featured on the vintage Kenner card as Snaggletooth and released as a POTJ figure as Zutton was identified as Zutmore in the Star Wars Insider. I can only find that one in the Holiday Special. Oh! And there's another one in the Richard Pryor Star Wars bar sketch that seemed like it had official help from Lucasfilm - and I'm not touching what he called that Snivvian!!!
Is it me, or is this just exhausting? Because we start getting into that "What's canon and what's not canon?" kind of conversation that just starts going around in circles. And based on all of that confusion, I'm not going to take Hasbro to task on this one. Lucasfilm had to sign off on the name. And it seems like it's been a mess keeping the names of these characters straight for quite some time.
