On Thursday, participating stores unveiled its newest Frappuccino drink. Called "Witch's Brew," the concoction contains a purple blend of "toad's breath," Starbucks said in a news release. Other ingredients include orange crème Frappuccino and swirls of green "bat warts" that are made with chia seeds.

The drink is topped with vanilla whipped cream, dusted with green “lizard scale” powder.

"We wanted to create a flavor that you might enjoy at a Halloween party," Starbucks spokeswoman Jennica Robinson said in the news release. "It gets a little bit of juicy-ness from the orange flavor."

The Witch's Brew continues a pattern of Halloween-themed Frappuccinos from Starbucks. Last year’s drink was called a Zombie Frappuccino, while the Frappula Frappuccino was sold in 2015 and 2016.
