McDonald’s Japan has apologised after a promotional stunt with Pokémon triggered frenzied fans to bulk order Happy Meals, leaving a trail of uneaten food in their wake.

McDonald's Japan has canceled a Happy Meal campaign that came with coveted Pokemon cards, apologizing after resellers rushed to buy the meals and then discarded the food, leaving trash outside stores.

The Pokemon Company and McDonald's have teamed up before, but not without attracting undo attention from would-be scalpers. Earlier this month, McDonald's Japan was forced to end its latest Pokemon Happy Meal promotion a few days early because the supply of cards quickly ran out amid chaotic crowds clamoring for the cards that came with them.
