Wet-Dry World

Wet-Dry World is the eleventh course in Super Mario 64. Considered one of the most bizarre levels in the game because of its strange themeing, Wet-Dry World is commonly associated with negative feelings and anomalous sightings.

Negative Emotional Aura
Wet-Dry World is said to have a negative emotional aura, felt within multiple players[1]. The reason is still unknown, but it likely has something to do with the stage's music and appearance. One report has shown a positive spiritual aura, most likely caused by the presence of Stanley.

Human Brain Diagram
Supposedly, there is a hidden texture of a human brain within Wet-Dry World's assets. However, there has been no credible source for this texture. Opposingly, some state that the stage is a human brain model, which could be Stanley's brain.
