The holidays get into full swing when international superstar Mariah Carey helps the "EM: HE" team create a Winter Wonderland in Pensacola, Florida for Finis Gaston and his niece and two nephews. The spirit of giving is all around, from the moment Mariah Carey steps off the "EM: HE" bus to give this deserving family the surprise of a lifetime to the snowy reveal as Christmas parade revelers dance to her new holiday hit, "Oh Santa!," and volunteers and the community welcome the family to their festively-decorated new home.
