Singapore, get ready — the viral Grimace Shake that has been trending across TikTok and social media is finally arriving at McDonald’s! But this isn’t just another menu item launch; it’s a full-blown Grimace celebration that brings together tasty food, collectible merchandise, and interactive experiences across the island. For anyone who loves a fun, social-media-ready treat and exclusive McDonald’s offerings, this is one campaign worth checking out.
The Grimace Shake Has Officially Landed
The long-awaited Grimace Shake, recognised worldwide for its vibrant purple hue and creamy texture, is now available in Singapore. Designed to be playful, nostalgic, and utterly photogenic, the shake features mixed berry flavours that perfectly balance sweetness and tang. This is a dessert-like drink built for sharing on Instagram and TikTok, but it’s also surprisingly indulgent for anyone simply craving a fruity shake with a unique twist.
One of the best things? Customers can upgrade a meal to include the Grimace Shake starting from just $1.85. That’s a small price to pay for a globally trending experience right in the heart of Singapore.
Mushroom Burgers Take Centre Stage
While the Grimace Shake is stealing the spotlight online, McDonald’s is quietly elevating its burger game too. The new Creamy Mushroom Deluxe is a serious upgrade for mushroom burger fans. It features thicker, juicier beef patties, more grilled mushrooms, and a creamy black pepper mayo that enhances the savoury flavours. For those who prefer the classics, the Creamy Mushroom Cheeseburgers have returned as well, available in double or triple patty options.
For anyone who loves indulgent burgers, this is a perfect opportunity to try an upgraded version of a familiar favourite without breaking the bank. The combination of hearty patties and umami-rich mushrooms is genuinely satisfying and makes for a meal that feels a little more special than the usual fast-food run.
Fan-Favourite Sides Make a Comeback
McDonald’s is also bringing back the Star Potato, a side that may fly under the radar but is undeniably addictive. Crispy on the outside and fluffy on the inside, these bite-sized potatoes offer a perfect alternative to regular fries. They are ideal for sharing or enjoying as a snack alongside the new mushroom burgers and Grimace Shake.
From 19 March onwards, the Creamy Mushroom Deluxe (single/double), Creamy Mushroom Cheeseburger (double/triple), Star Potato, and Grimace Shake will be available from 11am during non-breakfast hours. They can be found at all McDonald’s restaurants islandwide, including Drive-Thrus, McDelivery®, GrabFood, and foodpanda, but only while stocks last.
Collectible Grimace Merchandise
For collectors or anyone who enjoys limited-edition items, McDonald’s is rolling out an impressive Grimace merchandise lineup. Fans can grab these items starting at just $5.90 when purchased with a meal:
-
Grimace Tumbler — from 26 March
-
Grimace Plush — from 2 April
-
Grimace Puffer Bag — from 9 April
Given the popularity of these items, they are expected to sell out quickly. It’s a fun way to extend the Grimace experience beyond food and bring a little bit of the campaign home.
Interactive Grimace Hunt at Bugis Junction
For those looking for a more hands-on experience, Bugis Junction is hosting a real-life Grimace hunt starting 17 March. The installations aren’t just photo opportunities — each Grimace comes with a QR code that unlocks exclusive deals when scanned. It’s a mini scavenger hunt that combines a playful activity with tangible rewards, making it perfect for friends or family outings.
Drive-Thru Perks
If you’re planning a quick drive-thru visit, there’s a bonus waiting. From 19 March, customers spending a minimum of $10 at Drive-Thru outlets will receive a free Grimace car decal and unlock the Grimace Shake for just $2.50. This is an easy, value-focused way to enjoy the campaign without leaving your car. It’s perfect for anyone who wants to combine convenience with a little extra fun.
Value Meals Make a Return
For those who prioritise value, the Spicy Tomato McSavers™ lineup is back. This includes familiar favourites like the Filet-O-Fish, McChicken, and beef burgers, along with a new Spicy Tomato Ebi Burger. These options combine affordability with a little extra flavour, making them an appealing choice for regular McDonald’s visitors or anyone wanting a budget-friendly meal.
Extra Fun for Families: Super Mario Happy Meal
Families aren’t left out either. Starting 26 March, McDonald’s will offer a Super Mario-themed Happy Meal featuring ten collectible toys (new items released weekly) or a Mario activity book. This is a great opportunity for families to enjoy both the Grimace campaign and a classic Happy Meal experience while engaging younger audiences with themed collectibles.
