Nobody really know how Ancient Pokemon lived during far far time, it get you into all sort of wild imagination.
Maybe, maybe there was Apex predator scream tail, far bigger then current time jigglypuff, catching other ancient pokemon, about to shallow it, while other run away!
That's a story I would like to believe <w<
Funny how there been some inconsistency over how ancient jigglytuff were scream tail or just a very big jigglypuff, so I've just made them both heheh
