Duolingo has killed off its unhinged green owl mascot, Duo.

The brand confirmed his unexpected demise on social, stating: “Authorities are currently investigating his cause of death and we are cooperating fully. We’re aware he had many enemies, but we kindly ask that you refrain from sharing why you hate him in the comments.” 

On Instagram, Duolingo asked fans to include their credit card number in the comments under the announcement to “automatically sign” them up for a paid Duolingo Max subscription “in his memory.” 

The brand has changed its icon on social media to an image depicting a dead Duo with crosses in his eyes.
