Unroll the crescent rolls. Using 2 triangles, make 4 rectangles of dough. Cut each rectangle into very thin strips, about 10 strips per rectangle.
Cut each slice of cheese into 4 strips. Wrap 1 strip of cheese around each hot dog.
Using 4 crescent dough strips per hot dog, “mummify” the hot dog wrapped in cheese to appear as bandages. Make sure you leave room for a face! Place each mummy on a baking sheet.
Bake 13-17 minutes, or until the dough is golden brown. With mustard, draw eyes or a face of each mummy.
