Roll hot dogs in crescent rolls starting from the bottom of the hot dog and working your way up and tuck the top of the dough for the mummy hood. Do NOT overlap the dough! Pinch ends together to prevent unrolling during baking. Place on a cookie sheet lined with parchement paper.
In a small bowl, combine the egg, garlic powder, and seasoning. Using a pastry brush generously brush over each mummy.
Bake the mummies in a blanket for 10-12 minutes in a preheated 400°F oven. Enjoy!
