Preheat oven to 375 degrees F. Unravel the dough and separate at perforations. Create 4 rectangles. Press perforations together to seal.
Cut each rectangle lengthwise into 10 thin strips. Wrap 4 pieces of dough around each hot dog. Stretching dough completely around hot dog to look like 'bandages'. Leave a 1/2 inch wide space at the top of each hot dog, to reveal the 'face' of the mummy. Repeat with all hot dogs.
Place mummy dogs on an un-greased cookie sheet. Spray them lightly with cooking spray.
Bake for 12 to 14 minutes or until golden brown and hot dogs are hot.
Remove from oven and let cool for a couple minutes. Create the 'eyes' with two dots of mustard. Serve warm with ketchup and mustard. Enjoy!
