It's beginning to look a lot like Christmas in Springfield, but while Marge gets in the holiday spirit, it's bah humbug for the rest of the family. Disappointed that she is alone spreading the holiday cheer, Marge sends a letter to Martha Clause (guest voice Stewart) to help her save the family Christmas. Martha comes to the rescue and transforms the house into the North Pole chalet Marge has always dreamed of, but when the family is noticeably absent from the perfectly trimmed holiday home, she realizes that it's Homer and the kids who make the holidays special. Meanwhile, the Simpsons get ready to sneak away for a tropical holiday vacation in Hawaii, but surprise visitors Mr. Burns and Moe's new friend, Katy Perry (guest-starring as herself in a special live-action sequence) delay their getaway. Four special holiday tales will be spun.
