The exact recording behind this clip is not documented, but squeaky toy noises have been a staple of comedy and pet videos for years. The sound comes from a small reed inside a hollow rubber toy that vibrates when air is forced through it. Online, creators reuse the squeak as a reaction effect for animals, toddlers and animated edits, and it travels easily between short videos because it needs no words or context. Its instant recognisability keeps it popular for light, family friendly humour.
