Oh, I've seen plenty of stuff from other worlds! I mean, I wouldn't be much of a world traveler if I didn't, right? But I don't know anything about any holidays that formed here. But I guess for people who come from worlds without them, you could say it's like they were formed here? They have their own unique traditions and whatever when it comes to them, I mean. Like, how they aren't too fond of Valentine's Day here.
