BURGER KING will turn YOUR poop Green!

*Warning: AL JAZEERA AMERICA presentation*

Diners tucking in to the fast food chain's limited edition burger are claiming it is turning their poo GREEN.

Burger King decided to bring out a "spooky" version of its popular Whopper to mark Halloweenafter it released a black-gunned version in Japan last year.

Chefs in the west use natural colouring to make the bread black – while the Japanese use squid ink.

But it seems the burger has been turning people's poop a rather different shade than usual.

Twitter users have been sharing their experience – sometimes with photographic evidence.

One user wrote: "Yesterday I ate a Halloween Whopper and now the colour of my poop is blue green. Where my brown poo?"

Ryan Skeltis wrote: "#HalloweenWhopper #GreenPoop is a real thing. Don't get to scared after eating it like I did (sic)."
