Super Galaxy

Super Galaxy or  is the second course of World Star in Super Mario 3D World. It is a course based off the levels and missions of Super Mario Galaxy, including enemies like Octoombas. The Comet Observatory can be seen in the background. After the course is completed, Rosalina will be unlocked as a playable character. The course is unlocked by completing Rainbow Run and its own completion unlocks Rolling Ride Run.

Layout
The course takes place in space with Lumas, neon lights, and metal platforms. The main obstacles are Rotating Panels. The Rotating Panels are either red or blue, with each color rotating separately. Despite this, the Octogoombas standing on them will stay stuck on the side they rest on as they rotate.

At the end of the level, Rosalina and a few Lumas are found by the flagpole and will join the players in the "Course Clear" celebration.
