McDonald's Teams With Netflix's KPop Demon Hunters for New Limited Menu
The Derpy McFlurry's blackberry boba pearls signal a real ops test: two new meals, two new sauces, and branded photocards hit nationwide registers on March 31.

Two themed adult meals, two limited-edition sauces, a boba-topped McFlurry, and collectible photocards arrive at McDonald's restaurants nationwide on March 31 as the chain launches its collaboration with Netflix's animated film "KPop Demon Hunters."
The promotion centers on what McDonald's calls "dueling adult meals." The Saja Boys Breakfast Meal pairs a Spicy Saja McMuffin with a hash brown and a small soda. The HUNTR/X Meal comes with a 10-piece Chicken McNuggets order and Ramyeon McShaker Fries, accompanied by two new condiments: Hunter Sauce and Demon Sauce. Both meals include a collectible photocard and a QR-linked access card that unlocks exclusive digital content inside the McDonald's app.
The dessert item, the Derpy McFlurry, layers vanilla soft serve with blackberry popping pearls and wild-berry sauce. That three-component build is where shift managers should focus their pre-launch coaching. Unlike a standard McFlurry, which requires a single topping, the Derpy version demands sequenced assembly of two separate additions, making it the highest-touch item on the new menu. Crew trainers running pre-shift walk-throughs on March 31 should position a dedicated dessert crew member during the opening drive-thru rush rather than rotating the role mid-window. The boba pearls, unfamiliar to most crew members and guests alike, are the single detail most likely to generate order re-dos if training is skipped.
The Ramyeon McShaker Fries add a second prep wrinkle. The shaker-format seasoning means fries cannot be bagged and held the way a standard side would be; they must be assembled to order, adding a step to every HUNTR/X Meal ticket at exactly the moment volume is likely to spike.
For managers auditing POS systems before launch, confirming that app-linked promotional codes are correctly loaded is as operationally critical as inventory levels. A transaction that stalls at the register while a crew member searches for the right code extends service time for every car behind it in the drive-thru.
Allergen documentation deserves the same pre-launch attention as recipe cards. The Spicy Saja McMuffin, both new sauces, and the boba-topped McFlurry introduce flavor profiles that are new to the menu, and the popping pearls may prompt questions from guests with dietary restrictions. Posting updated allergen information at prep stations before the first shift on March 31, rather than pulling it together mid-service, is the difference between a clean launch and a scramble.
Inventory forecasting for the branded packaging elements, the photocards and access cards, carries stakes beyond a typical promotional item. A guest who arrives for a collectible and leaves without one is a social media complaint waiting to happen. Netflix's "KPop Demon Hunters" draws a mobile-first, social-active audience that documents experiences in real time. Stores that treat the photocard as an afterthought in their par-level orders will feel that miscalculation before the first weekend rush is over.
