The Shambow.

Winter can be gray. And dull. And gross. 

And in some places, really, really long. 

But we discovered, during this time people really look forward to the annual return of one McDonald’s classic to help them cope. The Shamrock Shake.

Building off social listening, we pinpointed one city with an extreme case of winter blahs and brought them something special—the ultimate beacon of positivity mashed up with this product for one unforgettable, sharable feel-good experience. 

Enter Shambow, the Shamrock Shake rainbow.
