This Universe has not one but TWO special inclusions! First off is its namesake 'Space Worm', the first I've seen of its kind, making this a hard marble to let go of. On top of that you have a nice asteroid belt in there, with the opal asteroids wrapped around the elongated opal moon. Add a couple of nice major planets and you have one VERY cool Universe marble! If your travels through this Universe give you some insight into the function of this 'worm', then please let me know, as these are a new and as yet undocumented discovery, so nobody really knows their purpose yet, if they even have one.
