On the first castle in the first world you should come to a door with a prize box and a tutrle, if you will, if you don't have a "Flight Mario", that's what i like to call em', hit the prize box and get the fether note: you have to be a "Grown Mario" to get it,hit the tutrle and fly up beside the wall until you hit an opening go in and hit the box and get flute(warp thingy) Don't forget to use it in the second world not the first if you want to go to the 8th world
