McDonald's is continuing its "Reindeer Ready" themed holiday campaign in the U.K. for a third year running, this time with an animated spot about a little girl and her "pet reindeer." 

The fast feeder started the campaign in 2017 with a spot in which a little girl saves her McDonald's carrot sticks for the reindeer and followed it up with an ad last year featuring Santa stocking up on the carrot sticks at the Golden Arches to feed his hungry herd. 

The new ad starts off as an animation about Ellie, who is eager to play a game of ‘'reindeers" with her older sister. But the teenager slams the door on her, and Ellie heads to the garden where she meets Archie the Reindeer. When Ellie runs out of "Reindeer Treats" to feed Archie, the whole family set off to McDonald’s to buy more—and there's a live action twist at the end that reveals that Archie may not be quite what you think, and the sister has a kind side after all. 

The spot is by Leo Burnett London, with animation by Againstallodds at Passion and James Rouse at Outsider helming the live-action segments. As part of the campaign, McDonald’s will be launching an "Archie the Reindeer" storybook, also available in e-book and audiobook form, and once again it will be handing out free carrot sticks on Christmas Eve. 

“This campaign celebrates the power of a child’s imagination which comes even more to life at Christmas time," said Chaka Sobhani, chief creative officer, at Leo Burnett London in a statement. "Kids have that incredible ability to embrace the magical side of Christmas and see wonder where we struggle to especially when teenagers."
