Jabba-Related Mighty Beanz
From left to right: Max Rebo, The Rancor, Slave Leia, Salacious Crumb, Jabba, Bib Fortuna, Gamorrean Guard, Han Solo in Carbonite
The Jabba the Hutt bean was actually one of the first to appear in stores, and it’s even one of the “visible” beanz (that you can see even without opening the package). But there are a number of other beanz from Jabba’s palace. Some of these have been available from the start (Max Rebo, the Rancor, and Slave Leia), while the others are only just now starting to show up in stores. I now have all of the Jabba-related beanz except for the Rancor Keeper, which I haven’t been able to track down yet. I had to resort to getting most of these on eBay, since the Star Wars ones are pretty hard to find in stores, and the new characters haven’t shown up anywhere that I’ve seen.
Mighty Jabba's Collection 
I would imagine that there are still plenty of characters to be released from Jabba’s retinue on the mighty beanz line. Anything that you’re particularly hoping for?
I’m going by this list:

I don’t know if they plan to make more in the future after they’ve finished up what’s on the list, but it’s possible. I think they’ve actually done a pretty good job in terms of selecting characters. Still, they could probably make an Amanaman or some of the other more obscure aliens, and I think a Jedi Luke would be a no-brainer.
