New Super Mario Bros.: 4-Ghost House

This Ghost House can be a little complicated. Near where you start is a door on a lower platform. You'll find an orange ? Switch which will make four item blocks drop down from the ceiling on springs. The second from the left will give you a power up. While they're still in the room, hop on one of the item blocks and it will pull you into another part of the Ghost House when the timer stops. To the right, you will find the first Star Coin. Throughout the Ghost House are yellow platforms with red stripes. If you stand on one, it will take you around the wall into the next room, but will not take you back. Here, you'll find a special type of ghost, called a Balloon Boo. They won't attack you if you face them and will follow you when your back is turned, like a normal Boo, but when you look at them, they start inhaling air and increasing in size, but deflate while chasing you. A ! Switch will make a door to a new room appear. Another ! Switch will make red platforms appear. Wall jump up them for the second Star Coin. From there, you can take the pipe up and over into a new room. Take the high door to the flagpole. To get the third Star Coin and access to the cannon, on the pipe you need red blocks to reach, stand on the pipe as Mini Mario. Wall jump up and to the right to a narrow area. Wall jump up that to see a door. Before entering the door, wall jump up higher to reach the third Star Coin. The door will take you to the red flag goal.
