Terrace (Super Mario Galaxy)
- This article is about the dome in Super Mario Galaxy. For the room in Treacherous Mansion in Luigi's Mansion: Dark Moon, see Terrace (Luigi's Mansion: Dark Moon).
- “You should go to the Terrace first. Please rescue the Power Stars in the galaxies you see there.”
- —Rosalina, Super Mario Galaxy
The Terrace is a dome in Super Mario Galaxy. It is the first dome that Mario or Luigi have access to, and is unlocked once the Grand Star from the Gateway Galaxy is recovered. The Terrace's exterior resembles an Earth-like atmosphere; it is grassy and sits on a plain-like patch of the Comet Observatory.
Inside, the Terrace has starry wallpaper with a castle design in silhouette. It is the most realistic observatory in the game, due to it not having a clear theme (such as Kitchen, Bedroom, etc.) and featuring an inside that looks like a real observation room would look like in the Mario franchise. There is a small telescope in the corner, presumably for looking at galaxies. It's possible that this is the telescope that once belonged to Rosalina's father, as mentioned in Rosalina's Storybook. As with all domes, the Terrace has a Pull Star in the center used to access its galaxies.
The main boss of the Terrace is Megaleg.
