Boo's Horror Castle

Boo's Horror Castle is one of the seven boards of Mario Party 9. The players ride in a magic carpet-like vehicle. The captain seems to be holding a lantern. The miniboss of this board which is fought in a boss castle is a giant Dry Bones. The actual boss which is fought at the top of the castle and through a Bowser Gate is the dreadful King Boo.

The players start out in the front yard of the castle. They ride up the steps and through the front door. They arrive in a room which they navigate through. The players eventually ride out the left side which is where the boss castle is and where the Dry Bones is fought. After that the players enter the castle again. The players eventually reach the the roof which they navigate through and finally reach the uppermost tower where the bowser gate and King Boo are located. One of the gimmicks here are the Boos that come out of mysterious pictures. These particular boos follow the players, and the boos also roll a dice. If they hit the captain player, the player will lose Mini Stars. The castle has many rooms such as: Lobby, Kitchen, Front Yard, Left Yard, etc. All the rooms may be a reference to Luigi's Mansion.
