You see, it was one thing that the ponies had an analogous holiday for Valentine's Day, even if it was in the summer time rather than upon the cusp of spring as the holiday he was familiar with took place. What he had not anticipated was, for lack of a better term, Pony Halloween. Don't get him wrong: winter solstices, autumnal harvests, national holidays, religious customs, all of that made sense to him. All of them were perfectly valid reasons for having any number of festivals during the fall. That was fine.
