Oh, I guess no one filled you in. Okay, well on some worlds? They have this holiday. Essentially this holiday is one where people dress up in ridiculous costumes so they can go around to their friends and neighbors and threaten to pull rude pranks on them unless they oblige them with snacks. They wear the costumes so no one knows who they are. So it's essentially a day where burglary is condoned by the community at large. Apparently it's for the kids.

But of course, they do it at night and I guess that makes it spooky. The Malnosso really are big fans of it, so they like to find ways to make it as absolutely terrifying as they can for us each year. Last year they dropped the Moon on us. It was mean and very angry looking. It took forever to fall and the whole thing was pretty much terrifying.
