A LEGO animated short film, "New Year's Hothin' Eve," which is not part of the official storyline, was released online as a component of the webseries LEGO STAR WARS: Celebrate the Season on December 29, 2021.
Across the snowy landscape of Hoth, AT-AT walkers advance, accompanied by Snowtroopers riding 74-Z speeder bikes clad in winter attire. General Maximilian Veers and his subordinates are hosting a New Year's party inside the passenger area of one of the AT-AT walkers. He then goes to the cockpit to be with the AT-AT pilots. Using macrobinoculars, they spot several rebels, including Luke Skywalker, positioned outside the gates of Echo Base.
With only two minutes remaining until the New Year, General Veers gives the order for his AT-AT walkers to launch an assault on the rebel base, which prompts the rebels to mobilize. Skywalker and another pilot get into their snowspeeders. Rebel snowspeeders head towards the approaching Imperial forces. Luke's snowspeeder fires several shots near an Imperial speeder bike, causing the rider to be thrown off. The rider's fall sets off a chain reaction, causing multiple other speeder bikes to fall.
The snowspeeders circle around the Imperials, resulting in one of the AT-AT walkers mistakenly firing upon an AT-ST walker. The AT-ST driver becomes visibly angry. Skywalker then uses his snowspeeder's tow cable to wrap around an AT-AT walker, causing it to collapse forward into the snow. Veers becomes furious, while the rebels, including Princess Leia Organa, Han Solo, Chewbacca, and C-3PO, celebrate.
With only one minute left until the New Year, Veers commands a second attack. Rebel snowspeeders disable another AT-AT walker by destroying its head. Veers, now enraged, assumes control of his walker. He succeeds in shooting down Skywalker's snowspeeder. However, Skywalker uses a grappling gun to climb the AT-AT walker and cuts a hole through the vehicle's underside. Both the rebels and Imperials watch with bated breath. Skywalker throws a detonator inside, causing an explosion that destroys the AT-AT walker.
The rebels celebrate their victory, joined by a mother wampa and her offspring. Veers is left stumbling in the snow.
