Haunted Dungeon is the 10th course in Super Mario: The Power Star Journey and is located in the black building on top of the mountain in overworld 2. The level is a haunted jail house overflowing with boos. Most of the cells are empty, but some contain enemies, coins, boxes, or a hidden passage. There are three floors to the prison, all looking similar, with lines of cells along the wall, and many boos. Almost all the stars require Mario to climb all the way up the small building. Happily this is one of the simplest, straight forward, and less fatal levels. Just like most other haunted level, this course contains both Big Boo and Big Mr.I.
