Preheat oven to 375°F and line a baking sheet with parchment.

Unroll crescent dough and cut into thin strips about 1/4 inch wide.

Wrap two or three strips around each cocktail sausage, leaving a small gap for the eyes.

Place on baking sheet and brush lightly with melted butter.

Bake 12 to 14 minutes until dough strips are golden.

Press two candy eyes into each mummy while still warm and serve with mustard.
