Young-hee also known as The Doll, is a small motion-sensing animatronic doll that was used in the Squid Game, most prominently during "Red Light, Green Light" and was also featured in the background during "Squid Game". Her eyes were able to scan the movement of players quickly to see if any of the players were moving after hearing "red light," all players who did so were eliminated, along with any players who didn't make it to the end in time. the rules are simple. The player can move if she says "Green Light" and stop when she says "Red Light". If a player moves when Young-hee turns around or does not cross the finish line within the given time limit, they will automatically get shot by one of the sniper rifles and eliminated from the game.
