>>43343065Jigglypuff was already gaining popularity as the third member of the "cute Pokemon trio" as early as 1997. There's a lot of Japanese merchandise from that period with the three of them on it (one thing in particular I remember seeing when I was in Japan was a disposable camera that had the three of them on it, but I can't find any images of it). There was even a manga about the three of them released half a year after the Clefairy manga.
