Burger King's Royal Perks Members can access until October 31 a ghost detector through the BK app to unlock a meal deal for two that includes the chain's new Ghost Pepper Whopper.
The limited-time burger features a classic flame-grilled beef patty topped with spicy queso, bacon, jalapeños, and ghost pepper cheese on a seasonally appropriate orange-and-black sesame seed bun.
Burger King, which has a history of leaning hard into spooky season, added that the ghost detector app also uses "electromagnetic fields" to help determine whether there's anything paranormal going on in a house.
The company didn't claim that it was accurate.
