Can one purple mascot cause this much chaos?

McDonald’s Singapore is bringing one of its most recognisable mascots back into the limelight this week, pairing the return of Grimace with the launch of a purple-themed treat that’s already generating buzz online.

The campaign, created in collaboration with Leo Burnett Singapore, kicked off last weekend when Grimace “took over” McDonald’s social media, posting a series of blurry selfies. The selfies were posted with strange captions such as "I loveee shake do u", "skateboarding is my passion. did you knowww I can land a sick kickflip" and "it grimace. I have bigg thumbs so sometimes there r typos." The lighthearted, chaotic content immediately caught fans’ attention, signalling that the purple mascot was making a comeback.

On Tuesday, the narrative continued with a playful Instagram teaser featuring a faux apology note which read: “Grimace, who’s visiting our office, accidentally uploaded a bunch of selfies. It’s all good, sorry for the disruption.” The caption added, “Apologies. We’ve all done it before. Anyway, who knows what else Grimace has in store? Stay tuned.” The cheeky, personable approach helped build anticipation while making fans feel “in on the joke.”

In a statement to MARKETING-INTERACTIVE, a McDonald’s spokesperson said "Grimace has always been a lovable and slight clumsy character. His unfiltered selfies reflect his fun personality." 

By Wednesday, McDonald’s extended the campaign into the real world. About 30 Grimace statues of various sizes appeared outside the Bugis Junction McDonald’s, giving fans the chance to snap photos with the character. The statues also featured QR codes where fans can scan to get vouchers for their next McDonald's meal. Grimace himself also made in-person appearances, interacting with fans and creating shareable moments that bridged the gap between digital and physical experiences.

Yesterday, the excitement reached its peak with the official reveal of two major offerings: the global-hit Grimace Shake and the return of the creamy mushroom cheeseburger. The Grimace Shake, a creamy purple beverage inspired by the character’s signature colour, cements the mascot’s central role in the campaign.

Alongside the new menu items are Grimace themed merchandise including a plushie, a tumbler and a puffer bag among others. A fan-exclusive launch party at its Grimace-themed Kallang restaurant further amplified awareness.

Furthermore, out-of-home placements, including Grimace-themed buses circulating across Singapore drove further interest. Created in collaboration with Omnicom Media agency OMD and in partnership with Stellar Ace and Adzymic, McDonald's took over digital out-of-home (DOOH) placements in Dhoby Ghaut, Bugis, Singapore Management University and selected CBD locations. Driven by a strategic vision to connect with Gen Z in fresh and engaging ways, the campaign transforms otherwise ordinary commutes into playful, rewarding experiences, seamlessly weaving brand engagement into the urban landscape.

As part of the campaign, which runs from 26 March to 8 April, commuters are greeted by dynamic screens displaying real-time bus arrival information, an eye-catching image of Grimace, and a prominent QR code. Scanning this code launches an AR mobile game that challenges commuters to catch as many Grimace Shakes as possible within 30 seconds. Successful players are rewarded with a McDonald’s treat that is redeemable exclusively through the McDonald’s app.

Complementing the DOOH bus stop activation are eight 3D topper buses by Moove Media, along with ads on four MRT trains. 

The gamified approach was designed to capture Gen Z's attention, driving user acquisition and app engagement among this digitally-native demographic, as well as interest in the Grimace Shake and character merchandise.

Adamson Alagan, general manager, OMD Singapore, said “The viral phenomenon of the Grimace Shake presented a unique opportunity to push the boundaries of OOH media, transforming passive exposure into active engagement. This interactive DOOH experience not only captures Gen Z’s attention in their frequented areas but also integrates gamification and AR to drive new app users for McDonald’s."

"The excitement for the Grimace Shake and our whole suite of Grimace merchandise brings a sense of nostalgia while creating fun, social-first experiences not just for long-time fans, but also for Gen Z fans," said a McDonald's spokesperson.

"Every touchpoint was designed to create moments fans could truly be part of, whether they grew up with Grimace or are discovering him for the first time. It's all about celebrating Grimace's quirky charm in a fresh, relevant way that sparks both connection and shareability," added the spokesperson. 

Grimace, long a staple of McDonaldland alongside Ronald McDonald and Hamburglar, has recently experienced a renaissance through viral online trends. His latest spotlight builds on McDonald’s Singapore’s previous character-led campaigns. Last year, Singapore fans got a first look at the McDonaldland Crew in a limited-time tour featuring Grimace, Hamburglar, and Birdie.

The campaign teased the crew on Instagram with partially revealed images and short clips, ahead of a December 2025 music festival and exclusive merchandise rollout. The McDonaldland Crew music festival was later held from 12 to 14 December at Plaza Singapura and offered meet-and-greets, interactive zones, and live performances from local musicians. Fans could also collect limited-edition items such as pocket pouch blindboxes, sticker sheets, and themed phone straps, while MyMcDonald’s Rewards members could redeem points for special collectibles.

New menu items complemented the festivities, including the cheesy jalapeño quarter pounder and chicken burger, truffle cheese McShaker fries, and desserts such as a cookies and cream pie with OREO crumbs and a tropical mango and pineapple cone, sundae, or McFlurry.
