Toy Time Galaxy

Toy Time Galaxy is a galaxy in Super Mario Galaxy. It is a location filled with toys that are made out of rainbow building blocks, presumedly acting as platforms. Colorful trains have been seen there. The Spring Mushroom is found here. Cosmic Koopas also appears here. This Galaxy is located in the Engine Room Dome. This Galaxy is inhabited by Gearmos (like the one in the Battlerock Galaxy). The galaxy has a planet that has a hommage to Mario and Luigi (Mario on one side and Luigi on the reverse side.)
