Jigglypuff is a round pink Pokemon introduced in the first generation of Pokemon games in 1996 and popularised by the Pokemon anime from 1997. In the anime, this particular Jigglypuff sings whenever it finds an audience, hoping to be heard to the end, but its song puts everyone to sleep. Annoyed, it draws on the faces of the sleepers with a marker. The scene repeated across episodes, turning the song into a shorthand online for anything soporific, from lectures and meetings to late night streams that lose their energy.
