 * Super Mario Galaxy - Sounds from this game are used in Dream Space Walk. Planets from the Good Egg and Gateway appear in the Dream Spacewalk event. Dino Piranha is a rival. His boss theme is used. There is also the bee suit. Also used in Dream Space Walk, a track called "Into the Sea of Stars". The Battlerock Galaxy is also used as a Dream Event location.
