The Burger King Whopper is getting a Halloween make-over.
The chain's signature hamburger is getting a new black bun that's baked with A1 steak sauce.
Burger King announced the new burger on its Twitter page, saying "something wicked is coming."
It's also coming with a few more calories and higher fat count than the regular whopper.
Burger King has already sold burgers with black and red buns in Japan.
