On Sunday night, language-learning app Duolingo's mascot Duo cheerfully mocked the (metaphorical) death of rapper Drake during Kendrick Lamar's Super Bowl performance, posting a crude animation with the caption, "drake after attending his own funeral on national tv."

Duo the Owl was known for his silly antics, reminding Duolingo users to complete their daily lessons. He debuted with the app in 2011.

Duo was fatally hit by a Tesla Cybertruck, the language-learning company announced this week. The snarky owl has been the face of Duolingo for over a decade. Why his sudden demise, and what's next?
