Pucca is the cheerful, mostly silent heroine of the Korean animated series Pucca, where much of her personality comes through expressive sounds rather than dialogue. Short clips of her laughter began circulating on meme soundboards and in short-form videos, where creators needed a quick, instantly recognisable cute reaction. Because the giggle is only about a second long, it fits neatly into edits, streams and chat reactions without interrupting the scene. Its continued popularity comes from that simplicity: it signals sweetness and amusement in a single, familiar sound.
