Dome

Domes are rounded buildings that appear in Super Mario Galaxy, Super Mario Galaxy 2, and Super Mario 3D World. They reside on the Comet Observatory. 
== Description ==
Domes are the main access points to Galaxies in Super Mario Galaxy. Upon entering a dome, Mario must use a pull star to enter a map of the galaxies that can be accessed through the specified Dome. They are not the only access points, as the Trial Galaxies as well as Hungry Luma Galaxies are not accessed through Domes, as well as Bowser's Galaxy Reactor. 
Polari appears in each of these domes, as well as a pull star which will take the player to a map of the Galaxies that can be accessed through it. The domes look individually unique inside.
