This sound is tied to One Piece, the long-running anime adaptation of Eiichiro Oda's manga, which began airing in 1999. Short intro and opening-related clips from the series spread widely through anime edits, fan compilations and social posts because they are instantly recognizable to viewers. Even when trimmed to only a few seconds, the familiar opening energy helps signal adventure, friendship and a big-journey tone. That is why the clip keeps showing up in meme edits, fan tributes and quick references to the series.
