LEGO® Horizon Adventures™ Aloy & Varl vs. Shell-Walker & Sawtooth (77037) – the set where two heroes take on mechanical beasts that definitely won't go easy on them. Build Aloy and Varl with swappable weapon upgrades (fire, chill, shock—pick your poison), then construct two seriously articulated robot creatures. Shell-Walker flexes posable limbs and detachable shields. Sawtooth? Fully articulated jaws, swiveling torso, and attitude to match. Includes scenic pieces to set the stage for epic showdowns. Ages 9+. Bonus: unlock digital content in the LEGO Builder app if you need more reasons to keep playing.
