Flowey is the talking flower from Undertale, the 2015 indie role-playing game by Toby Fox, where he first appears as a friendly guide before revealing a cruel and manipulative nature. His mocking laugh became associated with that twist, and it spread through Let's Plays, fan animations and gameplay edits as Undertale built an online following. Creators later reused it outside the game in horror edits and dark memes, where it works as a signal of villainy or a sinister turn. It remains popular because Undertale fans recognise it instantly, while newcomers still hear the menace in the tone alone.
