The parent company of Duolingo, the language learning app that has changed the language learning habits of millions of people worldwide during the Covid-19 pandemic, announced the death of the beloved mascot, the green owl. The loss of this iconic character, which has motivated users for many years with its witty reminders, has sparked a huge reaction on social media. So, why did Duo die? The internet’s favorite unserious mascot Duo, formerly known as Duolingo Owl, passed away. In the statement made by company officials, it was mentioned that the owl’s departure signifies a significant change in the identity of the application, and users will continue to use Duolingo with a different experience. The company updated their profile picture with an image of an owl with eyes closed with a cross mark and its tongue sticking out. Following this development, it became a subject of curiosity whether the platform will bring a new mascot or undergo a change process. WHY DID DUO DIE? The post also includes a “joke” mentioning that officials are investigating the matter. The post continues: “To be honest, he probably died while waiting for you to do the next lesson, but how could we know. We are aware he had a lot of enemies, but please don’t write why you hate him in the comments. If you can’t help sharing, please share your credit card number too so we enroll you in Duolingo Max in his memory.” The Duolingo mascot had gained a wide fan base, especially with its fun reminder messages and unexpected humorous approach. Users have expressed that the owl made the learning process more enjoyable and sometimes acted as a gentle pressure for forgotten lessons. Following the loss of the mascot, many people on social media shared messages in his memory to express their feelings.
