Grover and the Penguins. It was found by Baby Bear. Block No. 1 was found by Stiller the Elf. Unfortunately, it had a cookie in it and the Christmas Counter Downer is devoured by Cookie Monster. Stiller the Elf states that Christmas will never come as Oscar celebrates. Elmo states that he and Abby can believe in Christmas miracles as Stiller joins them. Their believing attracts the appearance of Santa Claus (Kevin James). Handel's Messiah appears as they find every box of the Christmas Counterdowner. Santa Claus then sings "You Gotta Believe" with Elmo, Abby, Stiller, Big Bird, Snuffleupagus, Ernie and Bert, Count von Count, Grover, Prairie Dawn, Baby Bear, Telly Monster, Rosita, Zoe, and Cookie Monster. Santa Claus then takes his leave as he quotes "Merry Christmas to All and to All a Good Night." After the story is over, Stiller the Elf and Stan the Snowball wish everybody a Merry Christmas.
