After killing all of Bowser's forces, strangely, a transport, (Millenium Falcon wink wink) appears at the edge of World 8. Mario gets on, thinking he gets a reward for rescuing Peach. But when he gets off, he is on the unknown system that Han and Chewie found traveling the galaxy. Name some good examples for levels on the world 9 system.
