Said by an shitty bird who is dangerous world-wide. He's an green owl which looks green, cute and innocent but in reality he fucking kidnap the users' family if they don't do their lession. It is said that duolingo's favourite language is Spanish. If you don't do your
spanish lessons he might come in your house, kidnap
your family or either vanish you.
That's why he says Spanish Or Vanish.
Person: I feel tired. I'll not do my
spanish lessons today,
after all ,
nothing will happen if I didn't do my lessons for 1 day.
Duolingo: *Breaks door* SPANISH OR VANISH?
