Starting planet
This planet is shaped like a giant skull and is surrounded by bones. If Mario spins on the eyes of the skull, he will get three Star Bits. There is a single pipe which takes Mario to the Spooky Speedster Planet. The background environment seen in this area is based upon that from Ghostly Galaxy.

Spooky Speedster planet
