McDonald's is bringing back its iconic Shamrock Shake — with the help of a beloved mascot's relative! McDonald's said Shamrock Shakes will return to participating restaurants on Monday, Feb. 10, the company said in a news release on Tuesday.

Uncle O’Grimacey, the Irish uncle of fuzzy purple fan favorite Grimace, is making his return to the Ronald McDonald universe. The character, who speaks in about the most stereotypical Irish accent you could possibly imagine, has been absent since the mid-1980s after debuting in 1975, returning occasionally to paint Ronald’s whole world green.

One of the most recognizable holiday treats at McDonald's is making its return, along with one of Grimace's relatives.
