Rosalina's Ice World is a track introduced in Mario Kart 7. It is the second track in Special Cup. The track is covered in snow and ice, as one might expect. The level has a Comet Observatory theme, containing many huts resembling the individual observatories. In addition, there is a needle-like spire resembling the top of the ship in the background. Hence the name, this course is owned by Rosalina.
At the beginning, there is a section resembling a half-pipe. One of the sides temporarily opens into the abyss. However, It leads to a lake and an iceberg that floats on its surface. If the iceberg is close enough, a kart can land on it. Otherwise, they use the propeller to move along the lake bottom. The iceberg contains several holes in it, potentially causing karts to fall into the water, and with speedy karts possibly going to crash into the edge. The lake below contains several swimming Penguins. The lake and the iceberg eventually lead into a cave containing icy stalagmites. There is an opening to the side of the tunnel that leads to an alternate path containing several Boost Pads next to a deep hole. The two paths reconnect before a ramp with a Boost Pad on it above a hole. Past the hole is the exit to the cave and beyond a bend is the finish line. This is the only course blatantly belonging to a female character that does not "advertise" that character (this course has no pictures of Rosalina, whereas Peach Beach in Double Dash and Daisy Circuit in Mario Kart 7 have billboards or posters of them). This makes Rosalina the only female character with a course that does not have any signs of her name or her picture.
Rosalina's Ice World strongly resembles Cosmic Cove Galaxy with the exception of Skeeters and Cheep-Cheeps. Gateway Galaxy from Super Mario Galaxy can be seen in different perspectives. The Starshroom can be seen on the track.
