A fictional object that looks
like a floating cube, pyramid, cylinder, etc. It can be used as a toy to watch a group of
short videos. The point of the videos is to try to guess the theme of them. It could be something
like "the five fingers" or "the five senses" or something like that. Graybles can also be used for emergencies. If you are in danger and you watch a grayble, it will show you a way to get out of danger. It might show an event that happened to someone else in that same place and you can learn from their mistakes or their successes, but you
never really know with a grayble. Graybles almost seem
like they have a mind of their own.
