LEGO Masters | 8pm | Fox

Repeat, two hours: 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 build decked out holiday houses filled with traps inspired by the fan-favorite holiday movie Home Alone. Then, the teams go head-to-head and craft an epic reindeer-replacement-build that puts a twist on Santa’s sleigh.
