For those of you who, in the w8 last castle, are running out of time because you just do the same thing over and over, you have to go on 1 the bottom slot, 2 the top slot, 3 the middle slot. After that it will bring you to bowser junior and giga-bowser.

I just can't get to any of the worlds that are blocked, in world 3, do I have to just jump on the monster, or just pound him with a cannonball when I'm a mini?

Do you have the problem with World 7 that when you complete 7-6, it just takes you back to 7-4?

Use the Bob-ombs to try and explode the blocks that are blocking the pipe, OR use a Mega Mushroom to crush the blocks. Then when you reach the red flag, you'll enter World 7-A. When you complete that course, you'll move on to the castle. Then you'll battle LakithunderSpoiler:

. Ta-DA! You've beaten reached the end of World 7!

You need to have a mini mushroom (blue one) on the bottom screen of your ds.
Enter the boss with fire balls. Hit him a few times, (twice) but before he dies you have to hit the blue mushroom on the bottom of your ds.
Get the blue mushroom, and this turns you into tiny mario. Jump on the bosses head once, but you have to jump on top of him and press down when you're in the air to pound his head. (normal jumping won't work).
Once the boss is dead, there is a little passage in the floor to allow you into worlds 4 and 7.

what you need to do to beat the bosses with mini mario is.. for example when you are fighting the boss that is gray and comes out of the ground and spits gray balls at you, when the boss gets all of the way out of the ground go to the other side,jump off the wall,get above his head and do a ground pound on his head.
