Mascot Swap: Duolingo x Brawl Stars

PR Campaign
Thursday 17th September, 2026

Duolingo and Brawl Stars swapped their famously chaotic mascots for a joint in-game event. Duo became a quiz-answering boss in Brawl Stars, while Spike appeared in Duolingo lessons, turning the crossover into a playful two-way challenge with rewards in both apps.

Why it worked: It weaponized a live, two-way mascot feud into timed, playable stakes—quiz damage in-game and streak-gated unlocks—creating event coverage, not ads.

The lesson: Consider hijacking an existing rivalry and shipping a time-boxed, interactive challenge with asymmetric rewards that force cross-platform participation.

FAQs

What is this?

Every day, brands launch PR campaigns and the media covers them. We scan lots of different news sources and use AI to spot the campaigns behind the stories, and show you which ones are getting the most traction right now. Think of it as a live leaderboard of what's working in PR.

Where does the data come from?

Finchling is a news monitoring tool that analyses lots of news from across the internet.

Does this track sponsored posts, or is it earned media only?

It's built to only track earned media - we use AI to filter out anything that we think is a sponsored placement.

What does "ranked by coverage" mean?

It's ranked by the volume of coverage that talks positively about the campaign. We count the outlets covering it, then give a boost to campaigns whose coverage is positive, and those with negative coverage drop down. We're not weighting by outlet size or reach.

Why isn't my campaign listed?

If you've launched a PR campaign recently and it's not included in here, and you think it should be - drop us a note and we'll investigate.
