Preheat the oven to 350 degrees.
Remove wrapping from corn dog and place in preheated oven for 10 minutes.
While corn dogs are cooking, unwrap crescent roll dough and flatten on a cutting board.
Use a knife to cut the dough into various strips and sizes.
Remove corn dogs from oven after 10 minutes and let them cool for a few minutes.
Start to wrap the crescent roll dough around the corn dog until it resembles a mummy form. Leave room on top to place candy eye sprinkles once it is done baking.
Place back into oven and bake for an additional 10-12 more minutes. Or until the dough is a golden brown color.
Remove from oven and let cool.
Attach the candy eye sprinkles with a dollop of mustard on the back and place on mummy dog.
Serve with mustard and enjoy!
