Big Boo's Haunt is a three-story mansion located in a small cage. It is the fifth course in Super Mario 64 and Super Mario 64 DS. Unlike most other courses, Big Boo's Haunt is not accessed via a painting. Instead, Mario must travel to the castle's courtyard (after he has collected twelve Power Stars) and defeat a Big Boo. The Boo will drop a small cage containing the course. Mario shrinks upon entering this cage.
Big Boo's Haunt is inhabited by none other than Big Boo himself. There is a small shack on the side of the mansion that has a lift to the basement. In the center of the basement is a strange large merry-go-round. There is also the Mad Piano (a piano that when the player gets close that attacks by trying to bite Mario since it has teeth). Big Boo's Haunt is also home to Big Mr. I.
Super Mario 64
Go on a Ghost Hunt
Mario must go through the entire course and kill every boo there. Once every boo is defeateded, Big Boo appears in the main room of the mansion. Once Mario has defeated him, a star appears on the second floor and a stair case appears from the ground to reach it.
Ride Big Boo's Merry-Go-Round
Once he enters the course, Mario should enter the shack near the mansion. He'll take the lift to the basement and hear "circus music" as he progress onward. There will be a door that leads into a room with a spinning floor and boo paintings around the walls. One near a doorway will shoot out fire while boos will appear out of one on the left side of the other doorway. After Mario defeats 5 normal boos, Big Boo will appear again and give up another star once Mario defeats him.
Secret of the Haunted Books
The third mission for the red capped plumber is on the second floor. Once Mario reaches the second floor of the Foyer, he should take the right hand door on the left side of the room. This will lead him into a library. As Mario heads around the library, small books (not to be confused with books with teeth that attack Mario in other rooms). Once the plumber has rounded the corner, he will come to a wall with three books jutting out of the wall. If Mario punches or kicks them in a specific order, the wall will move away revealing a door. If he hits the books in an incorrect order, a small book will attack him and the books will reset. Once he enters through the door, he will see a Power Star.
Seek the 8 Red Coins
As the title implies, Mario must collect eight Red Coins hidden throughout the level. Once he has acquired all the coins, a power star will appear on the the left side of the second floor of the Foyer over a Star Marker.
Big Boo's Balcony
Mario's journey next takes him to another encounter with Big Boo. He'll head up to the third floor. The plumber will see a door that will lead to the outside balcony were he will meet Big Boo. After his third defeat, Big Boo will give up another Power Star.
Eye to Eye in the Secret Room
Back on the third floor, Mario will see a wall with a picture of a boo. The power star he seeks is inside. What he must do is have activated the blue ! Switch and be able to use the Vanish Cap(Luigi must find a Power Flower In the DS version.). On the second floor is where the cap Mario needs. He needs to quickly acquire the cap and rush trough the wall on the third floor. Inside the wall is Big Mr. I. Once Mario defeats it, he will be rewarded with a power star.
Collect 100 Coins
The mustached hero needs to run around the entire course and collect at leased 100 coins to gain the final star in the course (as in every other one).
