ABC Family has started its annual "25 Days of Christmas" event on Dec. 1. In line with this, "Prancer" is a must-see when it airs.

The network commences the said event on Dec. 1, according to International Business Times. Various Christmas shows are aired and could be enjoyed by holiday fans, such as "Dr. Seuss' How the Grinch Stole Christmas," "National Lampoon's Christmas vacation," and "The Polar Express."

ABC Family, which is also having the new name "Freeform" in 2016, includes Jim Henson's "The Bells of Fraggle Rock," "Emmet Otter's Jug-Band Christmas," and some special behind-the-scenes preview of the new television series "Shadowhunters."

ABC Family's "25 Days of Christmas" is also set to run from Dec. 1 to Dec. 25. Sample titles that are expected to air within the timeline include  "The Preacher's Wife," "Disney's A Christmas Carol," "Mickey's Once Upon a Christmas," "The Life and Adventures of Santa Claus," "Frosty's Winter Wonderland," and "Rudolph and Frosty's Christmas In July," from morning to afternoon.
