Jigglypuff debuted in Pokemon Red and Green in Japan in 1996 as the Balloon Pokemon, a Normal-type known for singing a lullaby that puts listeners to sleep. In the anime it became a recurring gag, following Ash and angrily drawing on the faces of anyone who dozed off during its song. Its in-game cry, a short electronic squeak distinct from its anime voice, was carried across generations of games and later clipped for soundboards, where fans reuse it for cute, sleepy and fainting jokes.
