As well as giving the Ewoks some facial expressions (and hopefully a few scary ones) I've always wanted to see Jabba get a bit more articulation (especially around the mouth). He speaks a complex language yet his mouth does little more than flap open and shut and stick his tongue out, which was all they could do back then but hopefully Ady could weave some of the magic we saw in his cantina redo and give the big guy a smile, a smirk and a frown or two. He's suppossedly furious at the death of his Rancor but all he does is rock back and forth like a dog with worms (sorry about that mental image folks).
