The drowning theme comes from Sega's early Sonic the Hedgehog platform games, where it plays when Sonic is underwater and running out of air. Its rising, repeating melody was designed to warn players that only seconds remained, and it became one of the most recognisable sounds from the series. As gameplay clips and retro gaming videos spread online, creators began reusing it outside the games to signal any moment that was running out of time. It remains popular because the panic is instantly understood, even by viewers who have never played Sonic.
