Go to the doors ;)
First go to the world 3 last castle or world 6 last casltle if you are mini mario, then you beat bowser there is a little hole and it leads you to world 4 and 7.
To get to world seven you have to beat the big flying flower on the last castle on world 5 , if you can complete it using mini man (the small blue mushroom) you go straight to world 7 , however if you complete it without mini man you just go to world 6 OR.... You can complete the last castle on world 2 with mini man and this will take you to world 4 , if you manage to complete the last castle on world 4 you can get to world 7 that way , whatever suites you best.
you have to complete the last castle on world 5 as mini Mario :) have fun !
i don't know, i used an action replay
If you want to go to W4, complete the whole World 2 caste using mini mushroom. If you want to go to World 7, you have to complete the whole World 5 castle using mini mushroom.
Go onto world one level 4 and when this flying turtle comes hit the question box and a mini mushroom will come out. Or you could go to the red mushroom house and get a mini mushroom. And there is one last way you could go to world 2 last castle or world 5 last castle and there is mini mushroom in both of those castles. Also, there is a mini mushroom in world 7. I'm not sure which level, it's the one with the pipes, and if you want to know, message me.
you have to complete the last castle but you have to do it all in one to go back and unlock them.
you have to get a cannon from one of the worlds and go in it and boom your there
to get to world seven you need to beat the boss on the last castle of world 5 using mini mushroom.to get to world 4 you complete the last castle on world 2 with mini mushroom and beat the boss , once you unlock world 4 the cannon will also take you take you to world seven.
in world 5 in bowers castle beat the boss there as mini Mario to unlock world 4 ds version This answer is not true!!!! You go in world 5 bowers castle beat the boss mimi style but this one leads to world 7!!! To get there you do mini style on world 2 boss stage..
Well, if you are talking about New Super Mario Bros. for DS, you go the final castle in world 5 where you fight Petey Pirhana. Well, the thing is that you need to defeat him WHILE you are mini Mario or Luigi.
