Then, it’s the return of the dance marathon, “Dance Monster-thon.” All nine couples are set to join the ballroom floor at the same time, first dancing a Hustle and then the Lindy Hop. The judges will tap out couples from the marathon, one at a time. Couples earn additional bonus points based on how long they remain in the dance marathon, and the last couple standing will be crowned king and queen of “Dance Monster-thon.” Bonus points from the dance marathon will be added to the judges’ scores from the first round of dance to determine a final combined leaderboard of the night.
