The sleigh bells are jingling, the snowflakes are falling, and the jaw-dropping holiday-themed challenge has begun as four teams compete to win $10,000 for a charity of their choice. Returning LEGO Masters fan-favorites Christine Blandino, Stephen Joo, Aaron Newman and Corey D. Samuels pair up with celebrity builders Sophia Bush, Holly Robinson Peete, Eric McCormack and Lil Rel Howery for a tree-mendous two-night competition. First, the teams let-it-snow when tasked with creating holiday-themed characters that are placed on a LEGO Snowboard that will take a ride on the double-brick-diamond. In the final challenge, the teams craft a unique holiday story filled with cheerful characters that are turned into a one-of-a-kind build. The pair with the most impressive creation will win the grand prize for their charity and the coveted trophy.
