I don't know if anyone has seen this yet, but Toyfare magazine has a story on the never-released figures from the Star Wars Holiday Special. Apparently, these are right from a Kenner catalog.
These figures are listed: Itchy, Lumpy, Malla, Chewbacca in Life Day Robes, Chef Gormaanda, Holographic WOW, Ackmena, Saundan, The Ringleader and from his first ever appearance (Toyfare says that Boba Fett's first appearance was in the animated short during the Holiday Special) Boba Fett with Dragon.
If you haven't seen this yet, I would recommend reading it. Toyfare gives some very humorous commentary about the Special and shows some great photos of the would-be toys.
