User Testing
We set out to reintroduce Grimace to a whole new generation by tapping into the nostalgia McDonald’s fans still swear by. And if we were bringing back America’s Sweetheart, we weren’t going halfway. We built a full-on birthday celebration, anchored by McDonald’s first new shake flavor in nearly a decade. The result? A nationwide Grimace Birthday Meal that turned a cultural icon into a cultural moment.
Challenges
Turn around brand declines by engaging the future growth engine of the business, multicultural youth, increasing relevance and penetration.
Insight
Young people love celebrating birthdays, but the timeless magic of a McDonald’s birthday wasn’t a core memory for today’s youth.
Strategic Idea/Build
Invite America to celebrate Grimace’s Birthday.
Design Impact
We threw a month-long celebration of everyone’s favorite brand character, Grimace,with the ingredients to let youth make it their own. We also leveraged the playfulness of the character, and of course the iconic purple to make the visuals really stand out from the traditional McDonald's colors.
Solution
We tailored messaging by Grimace and food affinities, while celebrating diverse youth birthday traditions across digital, driving traffic into a fully purple’d-out McDonald’s app experience.
Results
Publicis One delivered 1.6MM+ additional Guest Counts, powering the strongest non-celebrity campaign to date and beating targets for app registrations, birthday capture, and engagement.
