There's a miracle on Sesame Street in this special holiday tale. Elmo, Abby Cadabby, and their new friend Stiller the Elf (voice of Ben Stiller) are going to count down to Christmas with the Christmas Counter-Downer. But all the counting boxes have gone missing and Christmas may never come again! Can Elmo, Abby and Stiller the Elf save Christmas? With the help of very special guests Sheryl Crow, Jamie Foxx, Anne Hathaway, Jennifer Hudson, Alicia Keys, Brad Paisley, Ty Pennington, Steve Schirripa, Tony Sirico, and Kevin James (as Santa Claus), Elmo and friends will learn to believe in Christmas miracles.
