Burger King is REALLY getting into the Halloween spirit with their latest menu item.
A GREEN Halloween Sandwich. It's called the "Nightmare King"...
It's basically just a chicken sandwich with bacon and cheese but it has this special GREEN BUN.
It's not only a weird color but it makes weird things happen to you! It gives you NIGHTMARES!!
Hence the name...
BK got some researchers to do a study on the sandwich and they found the people who ate it had 3.5 times more of a chance to have nightmares.
Check out the video on their experiment below!
