You know it's right around Halloween time when restaurants and food brands start rolling out black-colored items. The black burger buns are no stranger to Burger King menus, with the latest form taking shape as the Ghost Burger in Thailand.

The Ghost Burger is essentially Burger King's Rodeo Burger rocking a black bun costume for Halloween. Clever. The black coloring of the buns comes from cocoa, so no odd and unnatural food dyes here.

Burger King Thailand's new Ghost Burger is only available for a limited time and will sell for 119 Baht ($3.56 US dollars), or with two patties for 179 Baht ($5.36 US dollars).
