After Starbucks' first-ever black drink – the Phantom Frappuccino – launched last weekend, customers have claimed that the drink is turning their poo black!
Although the drink tastes fruity, to get the dark colour, edible charcoal has been blended into the mix.
And it's that which is giving customers the rather unusual side effect!
"Crafted with coconut milk, mango essence and ghoulish lime slime, this cold treat is just the thing to send shivers down your spine this Halloween," said the blurb.
"The Phantom Frappuccino is a blended beverage," Starbucks added. "It is dark on the outside and tastes like a light and fruity extravaganza on the inside."

However, it seems the side effect hasn't put some off of buying the drink.
The coffee shop has revealed that, due to popular demand, sales of the frozen drink – that was due to go off sale on Halloween – have been extended till November 3.
Priced at £2.70, the drink has received mixed reviews from coffee fans.
This is so cool!
