Mountain Dew’s new VooDew mystery flavor has been spotted at Hy-Vee and Walmart.

The new limited-edition Halloween-inspired mystery flavor is white in color, but its official flavor remains a real mystery.

The flavor will be available in two sizes – 20-oz. clear plastic bottles and a 12-pack of 12-oz. cans.

While the Mystery VooDew flavor is set to officially drop next week, some lucky fans have spotted the new Dew in the wild at Hy-Vee and Walmart.

Update: New Mountain Dew VooDew Mystery Flavor officially debuted at retailers nationwide today, Monday, August 26, 2019. I’m told the limited time flavor will “disappear just as quickly as it seemed to manifest. Get your claws on it while you still can.”
