Sonic Mania is a 2017 Sega platform game that returned Sonic to fast, side-scrolling stages inspired by the early Mega Drive titles, and its underwater sections reuse the series’ familiar low-air warning. When a character stays underwater too long, this urgent theme replaces the stage music and signals that air is nearly gone. Clips of that moment have circulated in gameplay videos, streams and meme edits, where the rising cue works even for viewers who have never played the game. Its familiarity and built-in countdown feeling keep it useful for any scene about running out of time.
