This jump effect circulates online as a public domain cartoon hop sound, credited in its file metadata to tramppa34 and Iwan Gabovitch. Its short elastic boing became popular with editors who need a clean, copyright-light jump cue for games, animations and short videos. Because it lasts well under a second and has no voice or music, it layers easily over footage and repeats well for bounce compilations. It is now commonly searched in Chinese as a duai jump sound and used wherever a quick, funny leap needs emphasis.
