Preheat the oven to 375ºF. If using crescent rolls, unroll dough, separate at perforations to create 4 rectangles. Press the other perforations to seal. If using dough sheet, unroll dough and cut into 4 rectangles.
With a pizza cutter, cut each rectangle lengthwise into 10 strips, making a total of 40 strips of dough.
Take one hot dog at a time and make a slit at the bottom for the mummy’s legs. Then, make two slits along the sides for the mummy’s arms.
Wrap strips of dough around the individual arms and legs and then around the body of each hotdog, leaving an area about a half an inch long where the mummy’s face is. Place the mummies on a large, ungreased baking sheet and lightly spray the dough with cooking spray so it bakes up golden brown.
Bake for 13-17 minutes or until the dough is light golden brown and the hot dogs are hot. With mustard or ketchup, draw two eyes on the mummy’s face.
