On my Nintendo DS, I've reached world 8 on the Super Mario gamebut cant get into world 4 or 7... help!?

Answer 1

To get Worlds 4 and 7, you have to beat the boss while you're Mini-Mario (get a Mini Mushroom). But if you jump and land on them, you won't do any damage. The solution: ground-pound on their heads.

Answer 2

I cant get past the boss on level 6- the one where the hamster thing is in a cannon thats firing at you! How did you get past that? You should be able to get to the other worlds, when youre looking at the map on the bottom touch screen use your stylus to tap on either one of the worlds and you should go there
