Inaccessible Level Painting



The Inaccessible Level Painting is an unknown location within Princess Peach's Castle, recorded in only a single image and uploaded to YouTube. The contents of the painting's level are unknown. The painting itself is blocky and difficult to determine, but the presence of two red dots atop a shadowy blob seem to indicate that the level would involve some sort of evil beast that Mario would have to face off against. The image is claimed to be from the lost 1995/07/29 build, but the veracity of this statement is debated due to the lack of concrete information regarding the beta.

Finding the Painting
In order for the painting to appear in-game, the player needs to ground pound each pillar in the mirror room (combination varies from copy to copy). The mirror will then slide down and the player will have access to the other side of the mirror. If the player enters the door on the opposite side, they will be greeted with a painting room similar to the one for Bob-Omb Battlefied, except the painting has been replaced with an almost entirely sepia-colored painting. The painting can not be entered, as whenever the player attempts to jump into the painting, they will fall back and a sound effect (shown in the YouTube video) plays every time the player attempts to enter it.

Theorizing
Some players believe that the painting may be a scrapped 16th course, as the placement and addition of a sound effect denying the player access to the painting implies that the player was going to be able to enter it at some point.

The painting could also be a part of the cancelled Disk Drive version of the game, as an additional course that would be playable in the Disk Drive version.

It may also be a result of cartridge corruption, which would explain the jumbled appearance of the painting and heavy resemblance the room has to the Bob-Omb Battlefield painting room.
