Young-hee is the giant animatronic doll from Red Light, Green Light, the first game in Netflix's South Korean survival drama Squid Game, which premiered in September 2021. When the song stops, her head rotates 180 degrees to spot any player still moving, and elimination follows instantly. Clips of that head turn spread across TikTok and YouTube as jump-scare memes, often remixed with horror edits and reaction videos. The sound endures because the series became a global phenomenon, and the doll's gaze is one of its most recognisable images.
