A "Sesame Street"-style retelling of the classic fairy tale "Cinderella," featuring Muppets Elmo, Grover and Kermit the Frog. When the "Princess's 18th Birthday Holiday Ball" turns into the "Princess's 18th Birthday Holiday Find-A-Husband Ball," all of the town's unmarried men and monsters make haste to the celebration -- except for CinderElmo. While the little red monster has always dreamt of dancing with the Princess, CinderElmo's stepmother has set her sights on the castle for her two sons, Telly Monster and Baby Bear. But with the help of a novice Fairy Godperson, a Prince of a Dog, his best friend Zoe and a can-do attitude, Elmo makes it to the ball and captures the Princess's heart. But When the clock strikes twelve, CinderElmo flees and the search is on.
