Perry the Platypus is the secret agent pet from Disney's animated series Phineas and Ferb, first aired in 2007, and his throaty chatter became one of the show's most recognisable noises. This baby version re-pitches that growl to an E note, which helped it spread beyond fan edits into general meme soundboards as a cute reaction clip. Its appeal lasts because the noise is familiar to cartoon fans yet works without context, sounding like a tiny animal trying very hard to be fierce.
