@supermegaultahypercoolguy4327 not exactly a creepypasta just a rumor about duo and how he'll kidnap your loved ones because of how aggressive the reminder notifications were
there's another version of the "last chance" one where it's just a closeup of duo's face with dark red lighting. probably the most terrifying one they have there's also one where duo is the dog from the "this is fine" meme
I’m gonna tell you a scary story while mostly scary-one time I didn’t do my Japanese lesson and Duolingo kept begging me to do it and I didn’t listen and then started counting down from one hour. I got super scared and then I deleted the app.😢
