Engine Room

"It might get a little rough from here on out, but just do your best and you'll be OK!"

- Gearmo

The Engine Room is a dome in Super Mario Galaxy. It is the fifth accessible dome, and will be unlocked whenever Mario or Luigi recovers the Grand Star from Bowser's Dark Matter Plant.

From the exterior, the Engine Room looks simply like a large metal dome, while inside there are purple and blue pipes leading up from a steel mesh floor. A Gearmo patrols the room, although he serves no real significance. As with all domes, the Engine Room has a Pull Star in the center, which is used to access the dome's Galaxies. Mario does not need to enter the Engine Room in order to reach Bowser's Galaxy Reactor, as he can just collect the sixty Power Stars required to access it from previous galaxies.

The main boss of the Engine Room is a more powerful version of King Kaliente.

Trivia

 * The Engine Room is the only dome in the game where an NPC other than Polari can be seen.
 * It is possible to gain access to the exterior of the Engine Room before completing Bowser's Dark Matter Plant by using the slope climbing glitch on the sloped roof of the Comet Observatory. As a result, the Warp Pad on the upper floor that connects to the Warp Pad next to the couch on the lower floor can be activated even before the Engine Room has been unlocked, allowing permanent access to the upper floor.
