Brawl Stars’ and Duolingo’s Iconic Mascots Face Off in New Collaboration

• Starting September 19, fans can compete in new events across both mobile apps, giving them a chance to see the iconic mascots — Duo and Spike — in new settings
• Brawl Stars introduces a new 20v1 Boss Fight, giving players the chance to take on increasingly powerful versions of Duo
• Duolingo launches a streak-based Quest, allowing learners to unlock exclusive rewards, including Spike

HELSINKI, Sept. 17, 2026 /PRNewswire/ — Today, hit mobile game Brawl Stars and the world’s leading mobile learning platform Duolingo debuted a global in-app face-off that brings the beloved green mascots — the Duo Owl and Spike — into each other’s worlds. From September 19 through September 30, Duo takes over Starr Park while Spike turns up inside Duolingo’s lessons, with new events and exclusive rewards.

The announcement follows weeks of the two trading jabs in the comments, a feud that spilled into the streets and the skies. It comes down to two green mascots fighting for the same thing: players’ time. Now the rivalry moves into both apps, putting the fight between Duo and Spike in fans’ hands.

Duo Takes Over Starr Park
Duo arrives in Starr Park as the game’s latest boss, inviting players into class to teach them a lesson… whether they asked for one or not.

• Boss Fight: For the first time, players can team up in a 20v1 Boss Fight game mode set inside Duo’s classroom. Players will have to work together to take down increasingly powerful versions of Duo while completing quizzes: those who answer correctly are rewarded, and those who answer incorrectly take damage or are eliminated.
• Daily Assignments: Alongside the Boss Fight, players can take part in a community-wide event to earn exclusive collaboration rewards. Step into Duo’s classroom to complete a lesson each day, then pass the final exam on the last day to unlock a reward. Misbehave, and detention awaits.

Spike Invades Duo’s Classroom
Spike doesn’t have Duo’s way with words, but he has other ways of encouraging learners to keep their streaks. As Duo wreaks havoc in Starr Park, Spike crosses over into Duolingo, where learners can complete lessons as part of a special limited-time Quest and unlock exclusive rewards along the way.

• Streak-Based Quest: Complete daily Duolingo lessons to progress through a special limited-time Quest, giving learners another reason to keep their streaks going while unlocking exclusive crossover rewards.
• Crossover Rewards: Duo may be taking over Starr Park, but Spike is making himself at home in Duolingo. Learners who finish the challenge unlock Spike in Brawl Stars.

Players can download Brawl Stars on the App Store and Google Play, and Duolingo on the App Store and Google Play to take part in the in-app events.
