The drowning theme first appeared in Sonic the Hedgehog, released by Sega in 1991 for the Genesis, and it has returned in many later Sonic games whenever Sonic stays underwater too long. Its short, accelerating loop became one of the series' most recognised warning sounds, separate from the main level music. Online, gamers began reusing it outside Sonic footage for any stressful countdown, last chance moment or impending failure, turning a practical game cue into a shared shorthand for panic that even non players quickly understand from the music alone.
