As any character on Tall Tall Mountain, go to the part where you find the red coins on the "Scary 'Shrooms". Jump off the opposite edge of the mushrooms where there is nothing but sky and, if the lifesaving winds push you up and after you are on land, go to the end of that road before the little incline and try to go off. If you hang on, drop and the winds will get you to the place where a sign is under that reads "road". Go in the middle and, if you do not hear a noise, move around that block. When you transport, the level will be underwater for a while (or until you reach the boundaries where it ends).
