Burger King wasn't joking when they tweeted "something wicked is coming."

Burger King insists it's not just the color... it’s also the flavor, with A.1. sauce baked into the bun. According to Burger King, it’s the sauce that turns the buns black.

Apparently that's not the only color change you experience with the new Halloween Whopper.

Some people are finding there's a weird side effect of the black bun on the Halloween Whopper . . . it's turning their poop GREEN.

 

 

 

 

I think the person who wrote this tweet is probably on to something...

 

 

Well played, Burger King... well played.

Now I want to try the Halloween Whopper. You too?
