If you defeat Bowser in the last castle then you go in a air balloon and she will say: ''Did i ever tell you about the secret world and then you get World 9. To get the levels in that world you need to get all the star coins in all levels of all worlds. If you have every star coin in world 1 you get world 9-1, if you have all in world 2 you get world 9-2 and so on!
