Be careful: This mystical monster might just turn you to stone.

What you need to do: First things first: the snake halo. Buy toy snakes, and spray paint them gold. Once that's done, sew or glue them all onto a hat or headband. Complete your costume with gold and silver makeup and accessories, and get white-colored contacts to make this mythical creature really come to life.
