Question

How do you get to the top of the balcony to fight big boo in super mario 64 ds?

Answer 1

Go to the second floor of the Haunted house and enter the door on the far right side (this is easiest with Mario)  go on the platform and hit the red '!' box and get the power flower.  Float up and toward the direction of the room's door, and you will see a secret ledge.  Land on it, and enter the door there.  You'll see Luigi's portrait, so keep going down the area and go through the double doors when you see them, which will lead to the balcony.

Hope this helped!

Answer 2

You must be mario and go to the second floor, Go to the farthest door.

If you you go to the bottom right hand corner, there will be a little platform and a red ? block

Get it, float straight up and you will see another platform higher up and a door

Go through the door and you will enter a room that has luigi's picture and stuff.

Go to the door to the right of Luigi's picture and Big Boo will be there to fight :)
