First at the Cantina enter the following codes, CL4U5H for Santa hat and red clothes, next enter, TYH319, for White beard Extra. Then go to the character maker. Use a human head and put him in the clothes, probably chose a red or green lightsabre, just for the holiday effect. Next you have to go to the Extras Menue, and Activate Disguse 3. Hope you have fun with your Santa man.
