’Stranger Things’ and Burger King Collaborate on ‘Upside Down Whopper’ | Eater

"This fast-food chain is staging a Stranger Things stunt by adding an “Upside Down Whopper” — literally a Whopper served upside down in show-branded packaging — at 11 locations starting June 21, alongside themed T-shirts, pins, crowns, and ketchup packets. The promotion ties into a Coke/Burger King app activation (scan a barcode on sodas to win merch, food, cash, airline tickets, a car, and a Stranger Things VIP experience) and is complemented by a DoorDash “Hopper Meal” deal that delivers a Whopper, fries, and small soda for $5 plus access to exclusive Season 3 content via the promo code “Stranger.” The stunt is one of many brand tie-ins surrounding the season’s July 4 release and leans more on nostalgic packaging and merch than on show-specific menu items or new flavors." - Greg Morabito
