Calm Beach Trail

Calm Beach Trail is the nickname given to an anomalous level found in some personalized copies of Super Mario 64. It is described as a rather linear and simple level, implying it was scrapped early into it's development, or was created through Dynamic Level Arrangement. As the name suggests, the level takes the appearance of a long beach with very little content to be seen. The level reportedly has no music, instead having an ambient track of the ocean.

Description
Calm Beach Trail has been described as a beach-like level with very few objects, though several have been reported, such as coins, and enemies such as Goombas and the unused Bloobers. Otherwise, the only other objects consistently reported are Power Stars, often found through 8 red coins or simply walking to the end of the level.

The actual level itself has been described as a fairly straight line, taking place on a beach with decorations such as umbrellas, folding chairs, sand castles, and palm trees, with nearby water that fairly consistently contains very little objects besides the aforementioned Bloober enemies and red coins when they are present.

Positive Emotional Aura
Similarly to other anomalous areas such as the Internal Garden and Flower Fields, Calm Beach Trail has been reported to be "calming" to the player, likely due to its nature as a quiet beach with few enemies. However, it has been heavily debated if this is actually anomalous or is just caused by the design of the level, in a similar manner to Wet-Dry World's Negative Emotional Aura.
