Indeed. It's certainly an interesting holiday; it doesn't seem to be directly associated with any sort of Pokémon mythological figure in particular. Stantler and Delibird are often depicted on cards and such, but there isn't a central figure that the holiday is associated with. I have to wonder if there's a reason for that. I've heard that other worlds have Christmas as well, so surely there's some common thread between all of them that could explain why Amestris no longer follows that religion.
