Layout
World 4-4 is a Ghost House level of Super Mario 3D Land, featuring strange puzzles and ghost enemies. The first part of the level features a dark hallway with a Boo that appears while nearing a lone coin. The winding path of invisible checkered platforms awaits Mario for the duration of the first half of the level. A large octagon-shaped room is where Mario finds himself after the invisible platforms; this room houses the level's Checkpoint as well. While in the middle of said room, five boos come to attack Mario, but a Power Star can be found in the middle ? Block. Taking the top-right path leads Mario to the last leg of the level. The last leg is similar to the first half with the invisible platforms, but this time, there is a Big Boo chasing Mario down. On the far side of this area is a door that leads to the Flag Pole.
