Not content with just a new shake, McDonald’s is taking a nostalgic turn by collaborating with design studio Krool Toys and Gumpy Function to create a brand-new Game Boy Color game called “Grimace’s Birthday.” In this retro-style game, players join Grimace on a skateboarding adventure through McDonaldland, collecting purple milkshakes and searching for his fellow mascots to throw a birthday blowout.
