Four remaining teams return to battle, and in round one, they'll be challenged to take Christmas intergalactic and show us what happens when Santa's in space. Then, they must bring world-famous Christmas songs like "Deck the Halls" and "Jingle Bells" to life in a huge edible creation. At the end, one more team will be eliminated with help from special guest judge, actor Devin Ratray, who played Buzz in Home Alone.
