The Starry-Night Skies

The Starry-Night Skies is a level found in some personalized copies of Super Mario 64. It is found on the Second Floor of Princess Peach's Castle, in the normally inaccessible painting depicting a night sky. The level itself is usually a large, night-time sky area similarly to Rainbow Ride. The music is to be reported to usually be a music box remix of Bob-omb Battlefield's theme.

Geography
The Starry-Night Skies usually consists of clouds of varying sizes reused from Rainbow Ride or Wing Mario Over the Rainbow, requiring the Wing Cap to traverse due to the large spaces in between the clouds. The skybox is usually an edited mix of the Big Boo's Haunt skybox and a cloud skybox. There are usually some structures scattered throughout the level, such as a ship from Rainbow Ride. The level's enemies are most commonly flying enemies, such as Fly Guys, though enemies such as Goombas have been reported to appear on the clouds.

Missions
Very few reports get many stars in this level due to the distance between clouds making it difficult to navigate the level, though some stars have been documented. Some reports say that Klepto, or an entity similar to Klepto appearing more similar to a stork, can appear holding a star, that otherwise functions the same as Klepto. Other stars that have been reported include but are not limited to a red coin star, a 100 coins star, a star for finding an airship in the level, and flying to a star out in the open using a Wing Cap.

Theorizing
The Starry-Night Skies is believed to potentially be a reference to Yoshi's Island, due to the stork, the level's music, the painting, and the overall theme of the level, though this is unconfirmed. It is also believed this level was originally the unused 32NIGHT level, and a remnant from when Super Mario 64 was a much larger game, due to the level being night-time themed and 32NIGHT's name implying it was a night-time level.

Trivia

 * While it could be a coincidence, the placements of the stars on the painting seem to line up with the notes for the "Song of Storms" from the Legend of Zelda: Ocarina of Time. Ocarina of Time has paintings of Super Mario characters hidden in an inaccessible room, and the games were in development at the same time, so the resemblance being an intentional reference is a possibility.Song of storms.png
