New Super Mario Bros. U: Sparkling Waters- Leaf -- Skyward Stalk

Zelda reference aside, this is a simple, but somewhat challenging level. A beanstalk appears and leaves grow out of it. They turn brown, wither, and fall off. Hop up the leaves and you'll go to the main level, which automatically scrolls up. The beanstalk grows taller, making leaves that will fall, so keep climbing up. Flying squirrels are all over the place. There's a Red Coin Ring in case you need a power-up. The Acorn Mushroom is very helpful. The first Star Coin is on the left side, over a curling vine. You can stand on the vine when it's curled up. Also on the left side is a pipe that spews coins. Above it is a platform shrouded by the clouds. The second Star Coin is here. Periodically, Goombas attached to balloons will appear from the bottom of the screen. The third Star Coin is high above a pipe on the right side. You can either try using the balloons from the Goombas to reach it or cling to the wall as a flying squirrel, then return to the beanstalk. It won't be long before you reach the top. Take the pipe to the flagpole, using another beanstalk's leaves to reach it. This opens the path to the Rock-Candy Mines.
