Black Garlic Doritos is a flavor of Doritos corn chips produced by the Frito-Lay company and distributed only in the Japanese market, intended to coincide with the Halloween season. The packaging displays a swarm of bats flying around outside a haunted house, with an overlay of a vampire snarling and looking over his shoulder at the black-colored chips.
The idea behind this chip being Halloween-themed is that garlic is often seen as a repellent against vampires.
