One Piece began as Eiichiro Oda's manga in 1997 before the Toei Animation series launched in 1999, following Monkey D. Luffy, whose rubber body made elastic sound design part of the show's comedy. Short spring effects like this tooing, similar to a classic boing boing cue, became easy to clip and reuse outside episodes. Fans shared them on soundboards and in edits, where the sound alone signals a stretch, bounce or goofy recovery without needing the scene, keeping it popular for anime memes long after broadcast.
