For a limited time only, Happy Meals aren't just for kids. McDonald's has teamed up with street fashion trend Cactus Plant Flea Market to launch a lunch box for adults, filled with popular sports toys.

"One day you ordered a Happy Meal for the last time and you didn't know it," McDonald's said on its Facebook page earlier this month. But the upcoming commercialization of fast food giants will give adults a chance to relive a part of their childhood. 

From next Monday until October 30, McDonald's will offer lunch boxes to the Cactus Plant Flea Market, where adults can enjoy childhood hunger. The box comes with snacks and cute McDonald's characters: Grimace, Hamburglar, Birdie and newcomer Cactus Buddy. 

Fans of the Cactus Plant Flea Market can also win merchandise by entering a raffle through the McDonald's app. " 

"We're taking one of the most memorable McDonald's experiences and reinventing it in a new way that's so important to our adults," said Tariq Hassan, director of marketing and customer experience for McDonald's in the United States. 

This isn't the first time McDonald's has teamed up with big names in pop culture to promote sales. In 2020, he collaborated with American singer Travis Scott, selling his favorite food: Quarter Pounder, fries and Sprite. 

In 2021, McDonald released BTS Food, a collaboration with the South Korean boy band. McDonalds can trigger memories for adults with its new happy food experience.  

"We're taking one of the most iconic McDonald's experiences and reinventing it in a new way that's so important to our seniors," said Tariq Hassan, McDonald's USA director of marketing and customer experience manager.
