New Super Mario Bros U: Meringue Clouds-4 -- Bouncy Cloud Boomerangs

Past the Parakoopas on the stairs are bouncy clouds, which move back and forth. You can get the Ice Flower here, which is helpful for dealing with enemies. Past the Piranha Plant are some clouds with Goombas bouncing on them. You'll soon see a set of four green pipes. The gap between two of them has the first Star Coin, shrouded by fog. Be careful, as there is a Boomerang Bro just ahead. It's standing on some blocks, one of which has a 1-up in it. Next is a line of item blocks and brick blocks. Parakoopas are bouncing around in the area and there are Piranha Plants and bouncy clouds below. Find a brick block you can break through to reach the clouds below. Around where the two clouds meet is a brick block with a vine. This leads to the second Star Coin. Use the POW Block to knock it out of the sky and it will bounce on the clouds below, where you can get it. Return to the main level using the green pipe. After that is a pipe making infinite Goombas, as well as a Red Coin Ring over bouncy clouds. Past the midpoint is another Boomerang Bro, with the third Star Coin nearby. There's a cannon hidden to the left of a low Piranha Plant next to a cliff. Next is a set of bouncy clouds with a couple of Goombas and some blocks. The brick block over the higher cloud has a Starman, so you can breeze past the Piranha Plants with ease. There's another Starman in the next item block if you still have the power. Just past the Piranha Plants is the flagpole. This opens the path to Meringue Clouds-6.
