To get to the special levels: you need to beat star world 5. You've probably noticed this by now, but all star world levels have a key. Get the key for this level and it will lead you to a star in the middle of the star roads. You enter the level and get to the platform that has the P switch on it. You hit the block that has coins going strait up (did you know you can control this stream of coins!?!?) when it gets to about 3 coins high, set it off to the right and wait until the music stops to let you know that the coins have run out. Then, hit the P switch, and run along the now stone platform where the coins are and run until you see a yellow platform with a yoshi coin on it and fly up. You will need to have a cape for this (and I always keep a yoshi too just in case I need an escape if I did it wrong. You will see mushroom blocks and a regular brick that will make it so you can not get past a pipe to go farther. You need to go closer to the mushroom blocks, get the best attempt at a run that you can, and then make mario duck when you reach the block again, and he should slide under it. You will have to do this one more time for another block, but then you should be up by the key and heading on to the special world!
