Separate the dough from its container and form it into squares (two triangles together). Pinch the seams closed.
Cut 8 even strips lengthwise with a pizza cutter. Starting at one end of the hot dog, wrap 4 strips around each hot dog, leaving a 1/2 an inch of the hot dog uncovered at the top for the mummy's head. Place onto a baking sheet.
Place into the oven and bake for 10 minutes; turn the mummies over and cook for another 7 minutes, or until golden brown. Remove from the oven and let them cool for a few minutes.
Add dots of mustard for eyes. Serve with ketchup. Enjoy!
