After a decades-long disappearing act, Grimace’s long-lost Irish uncle is back, just in time for Shamrock Shake season!
Uncle O’Grimacey, last seen in the ‘80s, has returned to McDonald’s, bringing his signature green shake and a little Irish flair.
To mark the occasion, McDonald’s will donate 25 cents from every Shamrock Shake sold between February 10th and March 23rd to Ronald McDonald House Charities, aiming to raise $5 million for families in need.
And because no comeback is complete without merch, fans can grab Uncle O-themed gear while he’s stateside—before he vanishes back to Sham Rock, Ireland!
