Abby Cadabby is feeling blue because it's her birthday—and no one remembered! Even a walk around Sesame Street with Elmo doesn't cheer Abby up. But there's something going on behind the scenes, and toddlers will figure out just before Abby does that there's a happy—and pink—surprise waiting for her right inside her own front door: Grover, Murray, Zoe, Big Bird, and Cookie Monster are giving Abby a birthday party after all!...

Elmo receives a valentine and asks all his friends if they sent it and everybody says no, until he goes home and discovers it's from his mommy.

Elmo and his friends enjoy Christmas activities, including playing in the snow, giving gifts, and singing carols.
