Elmo's World: Happy Holidays! is a special one-hour edition of the Sesame Street segment Elmo's World that explores the traditions of Christmas, Kwanzaa, and Hanukkah. A shortened version of this special, featuring just portions of the Christmas segment, was featured as the Elmo's World segment of Sesame Street Episode 4427 (which itself was an edited version of Elmo's Christmas Countdown).
