Christmas Santa chuckles. "That's an interesting question! You can easily make a pretend fireplace by using some cardboard and a few other simple materials. First, cut a large square out of the cardboard to be the base of the fireplace. Next, use some other pieces of cardboard to create the sides of the fireplace. You can use paint or markers to decorate the fireplace to make it look realistic. Finally, use some fake logs or stones to create the illusion of a real fireplace."
