Touch the platforms on the Gamepad at the beginning of this level to raise them and gain access to the next tier. On the third tier you can raise the platforms to find a Fire Flower in one of the blocks. Underneath the second platform you can drop down to the Stamp .
Continue to a wall that requires you to make the platforms pop out so you can climb to the top. At the top, go to the left where you’ll find Green Star #1 . Off to the right is the Checkpoint Flag and a Warp Box. In this new area you’ll need to step onto the moving platforms and blow into the Gamepad Microphone to make them move. Ride them to the far end then into the Cloud Cannon where you’ll be able to race through the clouds and claim Green Star #2 .
When you arrive back on the platform blow on the Microphone again to reveal the shadow of a block along the back wall, hit it for a 1-Up Mushroom then climb up. Here you can pop out three platforms, but only pop out two then blow on the Microphone again to move a platform to the third spot. Ride this platform down to Green Star #3 then head back up using the movable platform and pop out platforms to cap the Goal Pole.
You gain access to a Toad House after completing this level.
