A LEGO short film titled "Reindeer Walker", which is considered non-canon, was released online on November 5, 2020.
The short begins with Princess Leia Organa, Han Solo, and Chewbacca dashing across the icy combat zone outside of Echo Base amidst the Battle of Hoth. Two rebel pilots maneuver their snowpeeder around a formation of advancing AT-AT walkers, deploying a tow cable to wrap around the walkers' legs. After having encircled the Imperial walkers, the pilots then set off several lights.
The primary pilot, Luke Skywalker, turns on a red light, which in turn activates the lights attached to the tow cable, causing them to illuminate in shades of red, blue, green, and yellow. Leia, Han, and Chewbacca express their joy as the "Christmas" walkers proceed across the battlefield. Chewbacca also lets out a roar.
