The clip comes from Jigglypuff, the round pink Pokémon, as it appears in Nintendo's Super Smash Bros fighting games, where its light attacks are paired with soft, cartoonish pop sounds rather than heavy impacts. As short game sounds moved onto soundboards and into short-form video, the puff became a handy reaction clip because it is instantly recognisable, very brief and easy to drop over a visual gag. It has stayed popular for the same reason: it turns a hit into a joke without adding aggression, and it fits the playful tone of Pokémon-inspired edits and gaming memes.
