Cowboys Christmas Extravaganza powered by Reliant is a holiday show that mixes Dallas Cowboys game day energy with Christmas cheer. The 20-minute show lights up Tostitos Championship Plaza at The Star in Frisco, with the world-famous Dallas Cowboys Cheerleaders kicking things off. A Cowboys football legend lights The Star's 67-foot LED Christmas tree, and the light display is synced to original Christmas music, with pyro lighting up the sky.
