This was take from a site that says there was another Star Wars Christmas special! From 1982!!!!
It seems that little Christmas is more important to the Empire than you would think. An evil Jedi-type named Darth Tyrannus (Christopher Lee!) shows up and, with the help of his toady Mopee, kidnaps the young Wampa. Mopee is some kind of shape-shifter (we think Tyrannus describes Mopee as a "Clawdite," though that term is nowhere on the official Star Wars site) but don't expect any great morphing effects from a movie of this vintage. After a video generated flash of light, Mopee appears in his new form through the magic of editing. Tyrannus and Mopee take Christmas with them to Coruscant, the seat of the Empire.
Here is the link.
