In 2025, McDonald's also returned the seasonal Shamrock Shake to its menu, featuring O'Grimacey, Grimace's green Irish uncle. By blending nostalgia and limited-time offers, McDonald's aims to foster customer engagement, increase sales, and boost foot traffic for sustainable, long-term growth.

With its brightly colored, made-to-go-viral specialty shake, the McDonaldland meal draws from decades of cultural familiarity. Today, McDonald’s revealed its plans for a new menu item that will evoke memories of the past: The limited-edition McDonaldland Meal will hit the fast food eatery’s menu later this month.
