The Grimace shake has taken TikTok and the internet by storm. The bright purple shake is as flavorfully sweet and fruity as it is fabulously purple. So what does the Grimace shake taste like? Childhood. And it's only a blender away.

What Is the Grimace Shake?

This chilly purple concoction is a limited-edition shake from the Golden Arches that honors the birthday of the furry purple Mickey D's mascot. Why purple? To mimic furry Grimace's violet hue! McDonald's doesn't give away all its secrets, but the company alludes to the milkshake as being berry-flavored. Unsatisfied with that answer, I decided it was time to see what the hullabaloo was about over the Grimace shake.

What the Grimace Shake Tastes Like

Officially, the Grimace shake is described as a berry-flavored milkshake. But this official taste tester finds something a little closer to home in taste: Trix. Yes, the cereal that's just for kids that the pesky rabbit never could spoon up for himself.

Here's a reminder of what you find in Trix: flavors of raspberry, lemon, orange, wildberry blue, grape, and watermelon. So the Grimace shake sharing those berry flavors isn't too far off.
