If you've played the original Katamari Damacy, chances are you can view the constellations (Cygnus, Ursa Major, etc.) that you've previously made. If you have your Katamari Damacy data saved on the same Memory Card as your We Love Katamari data, an option will come up on the data screen for you to upload the constellations from the previous game.
