McDonald's introduces Grimace-themed meal and shake for limited time.

McDonald's is celebrating Grimace's birthday with a limited-edition Grimace Birthday Meal, which includes a Big Mac or 10-piece Chicken McNuggets, fries, and a new purple berry-flavored shake. The celebration also includes Grimace merchandise, a video game, and a social media charity campaign. McDonald's has been reintroducing classic characters like Grimace and Hamburglar to appeal to a new Gen Z audience. The fast-food chain is also reportedly adding a Cheesy Jalapeño Bacon Quarter Pounder to its menu soon.
