If you’ve spent any time on social media recently, you’ve probably seen it: Duolingo’s famous (and famously unhinged) owl, Duo, is dead.
The language-learning app announced the tragic (and hilarious) demise of its mascot in an X post that quickly went viral, racking up millions of impressions and sparking an internet-wide reaction. Major brands and creators wasted no time in joining the spectacle.
From MrBeast posting a video at Duo’s grave claiming, “I didn’t do it,” to KFC UK’s TikTok showing a Tesla Cybertruck running over Duo complete with what looks like green chicken, this campaign has taken on a life of its own.
But beyond the chaos, this stunt is a masterclass in modern marketing. Let’s break down why it’s working and what your brand can learn from it.
The idea of “killing off” a mascot isn’t new, but Duolingo’s execution is different. Here’s why:
Duo Already Had a Wild Reputation
Duo wasn’t a blank-slate mascot. The internet had already turned him into an obsessive, slightly terrifying character who would stop at nothing to make sure users did their lessons.
Duolingo leaned into this, making his death feel like another chapter in an ongoing, absurd saga rather than a forced marketing ploy.
It Invited Other Brands and Creators to Play Along
Viral campaigns don’t thrive in isolation. By leaving the “who did it?” narrative open-ended, Duolingo allowed brands and creators to join in and generate more attention.
MrBeast’s video, KFC UK’s Cybertruck stunt, and even organizations like Netflix got involved, boosting Duolingo’s visibility even further.
It Uses Unhinged Marketing Effectively
“Unhinged marketing” is a growing trend where brands adopt chaotic, meme-driven strategies to engage audiences. Instead of traditional, polished campaigns, they embrace absurdity and audiences eat it up.
By gamifying Duo’s resurrection (encouraging users to complete lessons to bring him back), Duolingo has made engagement part of the joke while still promoting its core product.
You don’t need to “kill off” a mascot to take notes from this campaign. Here are three key marketing takeaways you can apply to your own strategy:
Embrace Your Brand’s Personality
Duolingo’s success comes from leaning into its existing brand identity. If your brand has a fun, chaotic, or playful side, don’t be afraid to show it especially on social media.
Find ways to incorporate humor, self-awareness, or a distinct voice into your content.
Leave Room for Audience Participation
The best viral campaigns invite conversation and interaction. Duolingo didn’t just announce Duo’s death, it left the story open-ended, encouraging brands, creators, and users to react and create their own content.
Instead of just broadcasting content, create opportunities for your audience to engage, respond, or build on what you’ve started.
Make Your Marketing Feel Like Entertainment
This campaign works because it doesn’t feel like traditional advertising, it feels like a pop culture moment. The more your content entertains rather than sells, the more likely people are to share and engage with it.
Think beyond direct promotion. What would make someone screenshot or send your post to a friend? Create content that taps into humor, trends, or emotions.
What’s Next for Duo?
With the campaign still unfolding, it’s unclear when or how Duo will return but one thing is certain: Duolingo has once again proven its ability to dominate social media.

Social media has changed the way we consume entertainment. Instead of waiting for a new TV show to drop, people now follow creators who act out entire storylines in short-form videos. One of the best examples of this is Shawna the Mom, a skit-based account that has...
