The House of Doors (or World 4-Ghost.png) is the Ghost House and the sixth level of Pumpkin Boneyard in Newer Super Mario Bros. DS. It contains a maze of doorways, each set containing only one that leads to the goal.

The House of Doors is unlocked by completing Bone Marrow Road or Flimsy Gulch. Completing its normal exit will unlock Arachnid Charnel, and completing its secret exit will unlock World 4-Cannon.png.


There are many purple arrow signs in this level causing Mario to get trolled so whatever you do, avoid following them at all costs.


Star Coins

Star Coin: 1 for this star coin follow the guide from the secret exit.

Star Coin: 2 head to the third room where the five doors are head to the fifth door but don't enter it instead get a running jump from the platform there to find the second star coin.

Star Coin: 3 right before the Goal Pole you'll find 3 Warp Pipes enter the second one and you'll reach the third and final star coin.

Secret Exit

You first go into the second door at the start of the stage. Then, you hit the red ! button which adds blocks to the door you just went into. Enter the door that you entered. And you are way to Koopa Country, not only finding the secret exit but also the first star coin which you can reach with some wall jumps but watch out for the Boos below.
