Motos Mountain

Motos Mountain is a supposed course in Super Mario 64 that uses the unused Motos enemy. It seems to be similar to Tall, Tall Mountain, though it usually replaces Rainbow Ride, oddly. It is described as a tall mountain that seems to use several machine assets, implying it is a completed version of Motos Factory. The level seems to very greatly in reports.

Geography
Motos Mountain is described as a large mountain with several machine and robotic objects surrounding it, as well as a cave leading to a mine. It appears to use several Tick Tock Clock assets. Notably, the level tends to use the unused variant of the block that goes up and down that has 3 stripes on the sides instead of 2. The level varies too much in reports to designate any other parts of the level. The only regular enemy it uses is Motos, which are defeated by being thrown off of the mountain.

Theorizing
It is believed this level is a mix of the unused Motos Factory level and Tall, Tall Mountain. Why the Personalization A.I. chooses Tall, Tall Mountain to merge with Motos Factory is unclear, similarly to why it replaces Rainbow Ride.
