You know the 1-up mushroom outside the castle, aren't you?
If not do this :climb up the third tree from the waterfall then jump off from it(someone said you have to handstand on it but you haven't)and as quickly as you can crouch. If done fast enough the mushroom can't get you 'til you crouch or crawl it will go above and around Mario's head.
