Bring an extra dose of merry to your Christmas tree with this Star Wars ornament. The festively decorated house features Darth Vader and his Stormtroopers caroling, an oversized Death Star on the roof and an abundance of lights. Connect it to the Keepsake Power Cord (sold separately) for continuous light effect. Plus, it performs a synchronized sound and light show to the tune of the "Star Wars: Main Theme." No batteries necessary.
