(WRIC) — Burger King’s Halloween Whopper is making waves online.
While the bun is black going in, social media users are saying you’ll see green on the other end of the experience.
Now, the hashtag #GreenPoop is trending on Twitter:
Meteorologist Don Schwenneker at 8News affiliate WTVD-TV also said the Halloween burger left him feeling “haunted.”
The burger was first introduced in Japan last year, according to ABC News. The black bun offered in Japan reportedly got its black hue from bamboo charcoal. The American version doesn’t feature bamboo charcoal, though. Burger King says the sandwich’s dark color comes from the “smoky black pepper flavor of A.1. baked into the bun.”
“We tailored the flavor of the black bun to the American palate with A.1. sauce, a flavor this country loves, and we’re delivering it in a way that’s never been done before by baking it into the bun. It may look Japanese but it tastes like America,” said Eric Hirschhorn, chief marketing officer for Burger King Brand North America.
According to the burger’s nutrition facts, the food colorings and flavors used in the bun “are commonly used in the industry and within the safe and Acceptable Daily Intake (ADI) approved by the Food and Drug Administration (FDA).”
