yea i know, its also how you can get a p-wing from level 1-4..by the way, did anyone know that you can get a music box in level 5-1, and a jugem's cloud in 3-7? cuz i did. anyway, he also said it had to do with the pipe with the 3 in it, and the para goomba, and the para koopas, and some hidden block (not the white one)...but i'm not sure exactly how it works. it's not in the strategy guide here, so if i figure it out i'll let you know.
if i had a signature, it would be here..too bad i don't.
