Puss in Boots first appeared as a swashbuckling cat in Shrek 2, where his sudden switch to huge, pleading kitten eyes became one of the film's most recognisable gags. The moment, in which Shrek holds the small cat while he melts into an adorable expression, was widely shared in clips, reaction videos, and memes. It stuck because it plays on the same joke every time: a confident fighter disarmed by his own cuteness. Editors still reuse the sound to signal instant charm, affection, or playful surrender.
