Burger King's new hamburger doesn't just look scary. The restaurant chain says it may actually keep you up at night.
The "Nightmare King" is a quarter-pound beef patty topped with even more protein- chicken, cheese and bacon. Then there's onions and mayo all on a green sesame seed bun.
This isn't the first time Burger King has served a bun of a different color. There was once the black Halloween whopper.
