Flowey is a major character from Undertale, the 2015 indie RPG created by Toby Fox. His talking sound comes from the game's text dialogue system, where each character has a distinct voice-like blip instead of full voice acting. That design made the sound memorable among players and easy to reuse in edits, animations and meme clips online. It remains popular because Undertale has a long-lasting fan community, and Flowey's specific sound instantly signals his unsettling mix of friendliness and menace even in very short clips.
