It's Christmas Eve on Sesame Street! After putting out cookies for Santa, Elmo's dad tells him a bedtime story about his great-great-grandmonster Elmo and how Sesame Street was once an unfriendly street. Everyone was grouchy and there was no holiday spirit. With the help of Grandmonster Elmo's new friends, they try to find a way to bring back the holiday spirit in hopes that Santa would come to visit. They learn that all you need is kindness!
