Rubber ducks with built in squeakers have been popular bath toys for decades, and their distinctive noise became a staple sound effect in cartoons, children's shows and online videos. As short form comedy grew, creators began dropping the toy duck sound over pets, babies and unexpected objects to make a scene feel cuter or more absurd. Because the squeak is short, clean and familiar as a real world toy noise, it remains widely shared on soundboards for quick jokes and edits.
