Engine Room

The Engine Room is a Dome in Super Mario Galaxy. It is the fifth dome accessed. It looks simply like a large metal dome. Inside, however, are purple and blue pipes leading up from a steel mesh floor. A Gearmo patrols the room. As with all Domes, the Engine Room has a Pull Star in the center, which is used to access the Dome's Galaxies.
