New York (CNN Business) McDonald's Happy Meal might be for kids, but officially it's over the hill.

This year marks the 40th anniversary of the company's first Happy Meal , the kids meal that helped McDonald's achieve fast food supremacy. Today, roughly one in every four orders at McDonald's includes a Happy Meal, according to retail data tracker Sense360.

Each Happy Meal contains the option of a hamburger or chicken nuggets, a side like french fries and a drink. And a toy, some of which have become collector's items.

McDonald's is celebrating this milestone by re-releasing some of its most popular toys over the past four decades, including Ty Beanie Babies' Patti the Platypus and the Tamagotchi.will sell a "Surprise Happy Meal" in 90 countries that will include the throwback toys beginning today, Thursday, November 7, through Sunday, November 11.

Some of the Happy Meal toys McDonald's is bringing back for a limited time.
