New Super Mario Bros. U: Acorn Plains- Blooper -- Blooper's Secret Lair

This is a secret level, which is technically part of the same world as the level with the secret exit, but is located in part of a different world. This is part of the beach world of Sparkling Waters. The secret levels do not have midpoints. We take a pipe underwater. This level is filled with pipes, some with Bloopers hiding in them and some with currents. Some of the pipes with currents rotate around. Get the Fire Flower because you'll need it to deal with the several Bloopers in the area. Past the three pipes with Bloopers in them are two pipes with currents coming down from the ceiling. The first Star Coin is between them. Align yourself between the two pipes and swim up. The yellow pipe below has a current that may help you reach it. Soon after you'll see a set of rotating pipes to the left of the second Star Coin. Swim directly under the red pipe to the left of the Star Coin to reach it. Keep going to the right and you'll see a Red Coin Ring. The currents from the pipes along the way may help or hinder you in getting them. At the end of the area is a green pipe in the ceiling and a red pipe below with a Blooper. Go through the green pipe. This leads to another underwater area that is vertical. There are two Bloopers in the pipes to your left and right. There's a set of rotating pipes with currents immediately above you. Stay to the left. On the left wall are three green pipes stacked on top of one another. The lower one has a current. Take the middle pipe. Drop down for the third Star Coin and return the way you came before the two Blooper Nannies make life difficult. Swim to the top of the level, while dealing with a Blooper and lots of pipes with currents. The pipe at the top leads to the flagpole. This opens the path to a new world, Soda Jungle. We can save our game now. We get a message saying, "You got all the Star Coins in Acorn Plains! That's gotta mean something good, right?" We shall see when we collect more Star Coins.
