This massive mobile research station puts kids in charge of their own scientific missions as they drive across snowy terrain with realistic 6-wheel suspension and deep-tread tires built for Arctic conditions.

The rotating rooftop observatory helps explorers spot Arctic wolves and track weather patterns, while the fully equipped interior becomes their home base with everything needed for extended expeditions—a working laboratory for studying discoveries, a cozy living quarters with a kitchen and bedroom, and even a bathroom for those long polar nights.

Five explorer minifigures each have important jobs to keep the mission running, from driving and photographing wildlife to conducting medical checks and maintaining equipment.

Kids will love using the included snowmobile to create pretend play rescue scenarios, like exploring dangerous ice caves where three Arctic wolf figures—including an adorable pup—roam free.

Perfect as a birthday gift for boys and girls who love creative pretend play, truck toys, and STEM exploration, this expedition headquarters can be combined with other LEGO City sets (each set sold separately) to expand the polar adventures.

For an enhanced building experience, parents can help kids access the LEGO Builder app for helpful 3D viewing tools and progress tracking.
