Grimace, the big purple milkshake fiend, is back in the spotlight—and this time, he’s bringing his long-lost Irish cousin, Uncle O’Grimacey, along for the ride. As of March 2025, these McDonaldland mascots are trending harder than a TikTok dance, popping up in adult Happy Meals, Funko Pops, and nostalgia-fueled memes on X.
But why is McDonaldland making such a big comeback after decades in the fast-food vault? Gen Z and Millennials are eating up the nostalgia, while McDonald’s cashes in on retro charm. Let’s break down the rise and fall of McDonaldland, why Grimace and Uncle O’Grimacey are suddenly everywhere again, and whether this revival could turn McDonald’s into the king of fast-food branding once more.
The Rise and Fall of McDonaldland
McDonaldland debuted in 1971 as a whimsical fantasy world used in McDonald’s commercials and branding. The idea? Turn fast food into an immersive adventure with memorable characters like Grimace, the Hamburglar, Mayor McCheese, and the Fry Kids guiding kids toward their next Happy Meal.
McDonaldland featured an absurdly charming landscape—Apple Pie Trees, Thick Shake Volcanoes, and Hamburger Patches—designed to make the fast-food experience feel magical.
However, legal trouble struck in 1973 when Sid and Marty Krofft sued McDonald’s, claiming that McDonaldland ripped off their children’s show H.R. Pufnstuf. The 1977 court ruling forced McDonald’s to pay $50,000 and rework its marketing strategy.
Despite this, McDonaldland thrived throughout the 1980s and 1990s, cementing itself as part of childhood memories. However, by the 2000s, McDonald’s rebranded to focus on a sleek, modern corporate image. By 2003, the beloved McDonaldland characters were phased out, leaving Grimace and his pals on the sidelines for two decades—until now.
Grimace’s Evolution: From Villain to Viral Star
Grimace started in 1971 as a milkshake-stealing villain with four arms, meant to be a bumbling antagonist. But in 1972, McDonald’s rebranded him as a lovable, two-armed doofus, and he quickly became a fan favorite.
Throughout the 1980s and 1990s, Grimace appeared in TV ads, Happy Meal promotions, and even starred in The Wacky Adventures of Ronald McDonald VHS series. But after a quiet spell in the 2010s, he was largely forgotten.
Then came 2023, when McDonald’s launched a Grimace Shake promotion that went viral on TikTok. The #GrimaceShake challenge exploded, turning Grimace into a Gen Z horror meme and racking up millions of views.
Now, Grimace is the face of McDonald’s nostalgia-driven marketing, appearing in adult Happy Meals, Funko Pops, and even brand collabs. His resurgence is McDonald’s biggest mascot revival in decades—and he’s bringing reinforcements.
Uncle O’Grimacey’s Shamrock Shake Comeback
Enter Uncle O’Grimacey, Grimace’s Irish cousin who first appeared in 1977 as the official St. Patrick’s Day mascot for McDonald’s Shamrock Shake.
Decked out in a green hat, shamrock cane, and thick Irish brogue, Uncle O’Grimacey only appeared seasonally to hype up the Shamrock Shake before vanishing in the early 1980s.
Fast forward to March 2025—McDonald’s has officially revived Uncle O’Grimacey for its St. Patrick’s Day Shamrock Shake campaign, playing off the same nostalgia that brought Grimace back to life.
His reappearance marks a shift in McDonald’s branding strategy, as the company leans hard into its quirky, forgotten mascots to drive engagement.

Where Are the Rest of the McDonaldland Characters?
With Grimace and Uncle O’Grimacey leading the charge, could the rest of McDonaldland’s crew be far behind?
-
Ronald McDonald – The original fast-food clown, created in 1963, remains McDonald’s official mascot but has taken a backseat since 2016, when the “creepy clown” panic led to his appearances being reduced.
-
The Hamburglar – The mischievous burger thief made a brief return in 2023’s Super Bowl ad and 2024 Happy Meal promotions.
-
Mayor McCheese – The burger-headed mayor, introduced in 1971, last appeared in Funko Pop! form in 2020 but hasn’t been featured in ads for years.
-
Birdie the Early Bird – Introduced in 1980 to promote McDonald’s breakfast menu, she resurfaced in 2023’s marketing but hasn’t gotten a major push.
-
The Fry Kids – These living piles of French fries, first introduced in 1972, have been absent since the 1990s Happy Meal era.
-
Captain Crook & CosMc – The pirate-themed fish filet villain (Captain Crook) and 1980s space alien (CosMc) remain deep cuts in McDonaldland history, but with nostalgia booming, who knows?
Will McDonald’s bring back the whole gang, or are we only getting Grimace & Co. for now?
Signs McDonaldland Could Make a Full Comeback
Several clues suggest McDonaldland is gearing up for something bigger:
-
McDonald’s Q4 2024 earnings report showed a revenue boost from nostalgia campaigns, including Grimace promotions.
-
Leaked concept art in March 2025 suggested a McDonaldland theme park attraction could be in development.
-
Social media buzz (#McDonaldlandReturn) proves massive demand for more retro McDonald’s content.
If this momentum continues, McDonaldland could return as a major part of McDonald’s branding strategy.
