World 5-Ghost House is a level found in the game New Super Mario Bros.
This Ghost House has Broozers that can harm Mario, but can also be used to his advantage. To get the first Star Coin, Mario needs to let a Broozer break some blocks under him, so that he can Wall Jump to the coin. Next, Mario needs to run and jump to a door in the corner of a room. He should quickly Wall Jump to get the second Star Coin (the third Star Coin is in the secret exit). Then, the player should keep going up to find a platform that carries Mario up. It will then stop, wiggle around, fall down, and lastly, it will shoot up to the top. When Mario leaves the platform and goes through the door, he will be at the flagpole.
- Star Coin 1: Mario should have one of the Broozers break a set of blocks blocking the path to the first Star Coin, and then wall jump to collect it.
- Star Coin 2: When the player spots a door near the corner of the room, they need to jump to it. Inside the room, they must quickly wall jump to the coin before the six Broozers in the room destroy the blocks.
- Star Coin 3: This coin is in the secret exit. Mario should reveal the invisible blocks aforementioned, and then he should reveal the Beanstalk. Mario should avoid the Broozer and enter the door. Mario should stay on the right side of the platform to get to the coin in an alcove.
On the floor above the door that leads to the second Star Coin, the player should see three blocks together. Mario should get on top of them and jump on each one, revealing three invisible blocks. Next, Mario should get on those blocks. He should go to the middle block, then he must jump (or duck and jump if he is Super Mario's size), revealing another invisible block that contains a Vine. He must climb it, avoid the Broozer, and go through the door. There is another platform there that the player must ride. At the end of the ride there is a door, and through the door is the Red Flagpole. The Secret Exit opens a path to a Warp Cannon that shoots Mario to World 8.
