The name Mr Parker appears to be the label given to this clip on user generated soundboards, where short pet toy noises are uploaded for instant playback and sharing. With no confirmed character, film or series behind it, the sound spread purely as a reusable effect rather than a quote. Its appeal comes from how recognisable a squeaky toy is to dog owners, making it easy to reuse for pranks, pet videos and reaction memes where a single high pitched squeak can stand in for excitement, confusion or playful annoyance in edits.
