Bundle up for a brand-new “sister-sister adventure” in the world of Frozen!

In this exclusive trailer for the LEGO Disney Frozen Northern Lights special, Elsa, Anna, Kristoff, Sven, and Olaf are back for more wintry fun in four animated shorts.

The new stories feature the voice cast from the original movie, including stars Kristen Bell and Idina Menzel, but in LEGO’s unique animation style. Elsa and Anna set out on an epic adventure to restore the glimmer of the northern lights, which are barely visible in the kingdom of Arendelle.

“If the northern lights won’t come to us, then we’ll go to the northern lights!” plucky-as-ever Anna declares. Olaf’s definitely ready to go, though of course the snowman gets into some wacky antics along the way.

They’ll also face some treacherous obstacles on their journey, like avalanches, brutal snowstorms, and ice walls — all while Elsa’s powers are out of whack!

LEGO Disney Frozen Northern Lights premieres Friday Dec. 9 at 8 p.m. on the Disney Channel.
