Santa can be unlocked with the following parts:

Step 1: At the Mos Eisley Cantina, enter the following two codes: CL4U5H (for Santa hat and red clothes) and TYH319 (for white beard Extra).

Step 2: Go to the Character Customizer and create the proper costume. Use a human head, the appropriate red clothing and don't forget the red cap! Santa can wield the weapon of your choice -- we recommend the green or red lightsaber to seasonally complement his shiny red duds. (Remember, the color of his lightsaber decides whether his Force powers are naughty or nice.)

Step 3: In the Extras menu, activate Disguise 3.

Step 4: Enter the character-based level of your choice in Free Play.

Step 5: Spread holiday cheer to a galaxy in pieces.

Step 6: Should IGN find your lack of faith in LucasArts disturbing, you will be Force Choked. Your next younger sibling will get your gifts and get promoted to Admiral before Arvel Crynyd smashes into his or her bridge when the shields are down in the next LEGO Star Wars.
