McDonald’s Shamrock Shake Returns—And You Can Thank Grimace’s Long-Lost Uncle

Unless you’ve been living under a (sham)rock, you know that every March, McDonald’s releases its limited edition Shamrock Shake in honor of St. Patrick’s Day. What makes this year different than the rest? Well, Grimace’s long-lost Irish uncle will be delivering the shakes, of course.

In acknowledgement and celebration of the Ronald McDonald House Charity’s 50th anniversary, Uncle O’Grimacey will be going across the country to spread some Irish cheer and deliver minty deliciousness to eager Shamrock Shake fanatics.

Here’s the lore: This Shamrock Season celebration came to life when Grimace stumbled upon his family’s original Shamrock Shake recipe. That discovery sparked Grimace to reconnect with his vibrant, joyful, and generous uncle, Uncle O’Grimacey. Inspired to reunite with Grimace and support his favorite charity’s 50th milestone, Uncle O’Grimacey packed his bags and embarked on a journey from Sham Rock, Ireland. Now that he’s here, Uncle O’Grimacey is traveling coast-to-coast, spreading Shamrock cheer with fans everywhere and celebrating RMHC and their mission to keep families together.

Starting February 10, every Shamrock Shake sold will see 25 cents given to the Ronald McDonald House Charities with a goal to raise $5 million dollars, which could provide 50,000 overnight stays for families in need.
