Squid Game is the South Korean survival drama that became a worldwide Netflix hit after its release in 2021, following contestants in green tracksuits competing for a cash prize. The harmonizing moment became a favourite clip online because it captures the show's strange mix of childhood games, teamwork and danger, and short edits of the group singing spread widely on TikTok and other video platforms. It remains popular because the harmony is instantly recognisable to fans and works just as well as a joke about friends sticking together as it does about a plan going wrong.
