• Duolingo's owl mascot, Duo, has undergone a controversial redesign. The owl appears sick with a runny nose, drooping eyes, and sweaty face. This change is a marketing strategy intended to boost user engagement by grabbing attention. Despite the alarming new look, the app and Duo's in-app appearance remain unaffected. Users have had mixed reactions - some find the latest look creative, while others are disturbed or confused by the sickly appearance.
