Gonzo is challenged to spend one night in The Haunted Mansion on Halloween night.

While on a grand world tour, The Muppets find themselves wrapped into an European jewel-heist caper headed by a Kermit the Frog look-alike and his dastardly sidekick.

When Kermit the Frog and the Muppets learn that their beloved theater is slated for demolition, a sympathetic human, Gary, and his puppet roommate, Walter, swoop in to help the gang put on a show and raise the $10 million they need to save the day.

The one-hour television event takes viewers on a musical journey filled with joy, heart, and laughter as the acapella group performs some of their holiday favorites. Special guests include Jennifer Hudson, Brett Eldredge, ventriloquist Darci Lynne Farmer, and Jay Leno.
