Duck quack effects have long been a staple of cartoons, toys and children's media, and this little duck version became popular online as a wholesome alternative to louder meme sounds. Its repeating, toy-like quacking spread through short animal videos, family-friendly edits and soundboards where creators needed an instantly recognisable cute cue. Unlike a single realistic quack, the extended sequence works as both a sound effect and a mini loop, which is why it is still used for baby animal clips, bath time jokes and light reaction edits.
