|Normal Ghosts||Meteor Ghost|
After successfully exiting the Astral Hall, Luigi found himself in the Observatory. He noticed an antique looking telescope in the room, and decided to look through it. Through the view, Luigi could see the Moon. After he had finished looking at the telescope, the walls in the room mysteriously faded away, allowing Luigi to step out on a small balcony. Small yellow Meteor Ghosts were falling outside, and Luigi decided to suck one up and shoot it at the Moon. The Moon subsequently exploded and a winding, ephemeral bridge appeared, allowing Luigi to step out into space and retrieve Mario's Star, the third item he would need to take to Madame Clairvoya. After the Observatory walls vanished and Luigi got his brother's star, he noticed that the telescope that he prevously looked through turned into a pile of crumbled wall, and could no longer see into "space" when the room is already cleared.
The telescope is the only real object in the Observatory, apart from a small dresser with a globe on top near the door.
- If one looks at the Mansion map while Luigi is on the bridge or small planet, Luigi's head will be way off of the map to the east.
- By using any Element, one can see that "space" does not extend forever. By shooting an Elemental Blast at the far wall, the blast will eventually hit the back wall.
- Stangely, Luigi cannot fall off the bridge. If Luigi could fall off though, it might have made Luigi either die or land in another room.
- Oddly Luigi doesn't need air to breathe in space.
