McDonald's has opened stores in an old train car, an airplane, and an oversized Happy Meal box. This new project from the corporation has many of the features of a regular restaurant—down to the posters advertising special menu items—but it's different in a major way. Instead of catering to human clientele, this miniature McDonald's is designed to attract bees.

McDonald's Sweden collaborated with the creative agency NORD DDB to build the branded beehive for World Bee Day on May 20, AdWeek reports. From the outside, the model is a replica of a McDonald's restaurant, with drive-thru windows, outdoor seating, and the golden arches presiding above it all. But instead of a counter and a tables, the interior is filled with frames where bees can build their wax. It's being billed as "the world's smallest McDonald's," but according to NORD DDB, it's still big enough to house thousands of bees.

The fast-food beehive is a nod to an initiative gaining traction at McDonald's in Sweden. Some McDonald's restaurants have installed beehives on their roofs and started replacing the grass on their properties with flowers to attract the pollinators. Global bee populations have declined at alarming rates in recent years due to pesticides, disease, and climate change, and the beehive project from McDonald's Sweden is just one creative way people are trying to give bees a boost.

This particular beehive won't be housed above a burger joint. On May 21, it was auctioned off to raise money for the Ronald McDonald House.
