New in: McDonald’s Singapore has officially launched its new Grimace Shake and exclusive Grimace-themed merchandise!

McDonald’s McGriddles Are Returning On 19 March

For those who are unaware, Grimace is a popular character from the McDonald’s universe, loved for his large, purple, furry appearance and his friendly, somewhat clumsy personality. Over the years, he has been a part of various McDonald’s campaigns, often seen alongside Ronald McDonald and other characters, such as the Hamburglar and Birdie.

The Grimace Shake, inspired by his sweet nature and purple appearance, is said to be a mixed berry flavour. The price starts at $1.85 for a meal upgrade.
