Burger King just unleashed a new seasonal offering that is making quite the splash this Halloween.
And though it will satisfy your sweet tooth, the Frozen Fanta Scary Black Cherry slushie is terrifying.
Like the name suggests, the item is black in color and is doing a number on the digestive tract of customers.
It's nothing harmful. That we know of.
This user tweeted about their satisfaction over the Frozen Fanta flavor in the spirit of Halloween. But great taste comes at a great cost.
"Prepare for very sweet & artificial with a subtle aftertaste and interesting odor. + Dyed tongue," wrote @JamesPopStar.
But the worst is yet to come.
Apparently, the black liquid entering your body exits as a different color.
After consuming the slushie, customers reported seeing their poop being expelled in colors of either green, blue, dark blue or even neon blue.
Regardless of the hue, the waste's color is definitely beyond the expected spectrum of a normal stool.
The concerns were real.
The new Fanta flavor is stirring up a fright. This customer even started to question his health.
"OMG... I spent all morning thinking I had some sort of infection in my colon or something!!!," wrote @jareology.
Those who survived the aftertaste issued their friendly warning.
Comedian Michael McBrine thanked Burger King for their service.
The unpleasant side effect isn't turning customers away from the product at all.
If anything, the social media reaction is incentive enough for brave customers to give the Fanta slushie a test run.
As they say, you can have it your way.
Burger King responded to the green poop phenomenon by tagging Charmin toilet paper. Now that's marketing synergy!
The bathroom tissue company tweeted back, declaring: "We were born ready..."
When the Thrillist asked for a comment from the fast food joint, a rep said, "For those who want to know, try it and find out."
The drink is offered for a limited time, but it will remain after Halloween through November 12 - for those who are just dyeing for seconds.
