Roll each roll into a 15-inch snake, leaving one end a little thicker for the head. Using a knife and a toothpick, cut slashes and poke holes to decorate the body of the snake. On larger end of snake poke holes for the nose and slice a 1 1/2-inch opening for the mouth. Crinkle up the aluminum foil and place in mouth to wedge it open during baking. Cut slashes across the tail section to resemble a rattler.
Wrap snake around a frank and place on a large sprayed baking sheet. Poke deep holes for eyes and press currants into them.
Brush well with egg and let rise for 15 minutes. Bake at 350°F for 15 to 20 minutes or until golden brown. Place on a cooling rack and carefully remove foil.
Poke a 3-inch piece of licorice into the throat. Clip the end to make it look like a forked tongue.
