From the Super Mario Wiki, the Mario encyclopedia
Starlight Cape is a location in Paper Mario: Color Splash. It is located east of Tangerino Grill. Mario, Huey, and the Sunset Express conductor help the Sunset Express arrive at Starlight Cape after Larry hijacks it. Mario and Huey arrive, and they admire the sunset when they see a shooting star. Huey wishes to find the rest of the Big Paint Stars, and the orange Big Paint Star descends afterwards. Huey reassures Mario that his wish, that Peach is safe, has also come true. Starlight Cape can be revisited by riding on the Sunset Express again.
