Obake Yashiki BGM

Reuses
The following list does not include ports or remakes of Super Mario World.

Super Mario Galaxy 2
In Super Mario Galaxy 2, the theme heard in Haunty Halls Galaxy and Boo Moon Galaxy, titled 「ゴーストコンベア」 (Gōsuto Konbea, "Ghost Conveyor"), is an arrangement of "Haunted House BGM". While Mario is riding Yoshi, shaker and percussion is added. The theme was arranged by Mahito Yokota.

Super Mario Maker
In Super Mario Maker 2, "Haunted House BGM" is given an original, more ambient arrangement for editing Ghost House-themed courses in the Course Maker, using eight tracks that fade in and out randomly to create a dynamic mix.

"Haunted House BGM" also receives new percussion parts for when Mario rides a Yoshi in the Super Mario World style, as this was impossible in such levels in the original game. Like other themes in the original Super Mario World, the theme adds to the instrumentation in its "Yoshi" variation.

Both of these new arrangements return in their original capacities Super Mario Maker for Nintendo 3DS and Super Mario Maker 2.

Super Mario Maker 2
