Starbucks new Halloween Frappuccino may be its most frightful yet, with tangy fall flavors and a terrifying form that conjures the undead.

The Zombie Frappuccino blended beverage has a ghastly green body made with Frappuccino Crème infused with flavors of tart apple and caramel and topped with pink whipped cream “brains” and red mocha drizzle. The creepy concoction is available October 26-31 in participating stores in the United States and Canada, while supplies last.

Starbucks has celebrated Halloween in stores with spine-chilling Frappuccino flavors since 2014, starting with the Franken Frappuccino blended beverage, followed by the Frappula Frappuccino in 2015 and 2016.

“When brainstorming a new Frappuccino flavor for this Halloween, we started by thinking about a Halloween party and monster mash,” says Jennica Robinson from Starbucks beverage development team. “We had already invited Frankenstein and vampires to the party, so we came up with another monster that could join the bash.”

For the flavor, Robinson returned to the monster party theme.

“We thought about what you’d serve at a Halloween party, and we settled on dipped caramel apples,” she said. “It has a tart green apple favor balanced with a smooth, sweet caramel.”
