Comet show
Complete levels in the game with a good time until all the comets are unlocked. When a comet is unlocked, it will streak through the sky and a button will be indicated. Fly into the sky from the hub screens to reach the Cosmos screen. Press the button shown earlier to see that comet again.
Alternate title screen
Successfully complete the game.
Alternate start up sounds
Depending on which file you choose at the load screen, "Na", "M" or "Co", you will get a different start up sound. They are cats meowing for the first file, cows mooing for the second, and chickens clucking for the third.
Original Katamari Damacy constellations
Have a saved game file Katamari Damacy on your memory card to unlock an option at the data screen that will allow you to import your constellations from the original game.
Comet storm/alternate cosmos perspective
Earn all the comets then visit the Cosmos screen. Press the corresponding buttons to "shoot" all the comets (the order does not matter). You will see a comet storm followed by a shift in perspective. This new perspective displays the cosmos as two perpendicular orbits.
Control loading screen
You can move the King's head to see what he is saying on the loading screens by pressing the [Analog-sticks] in the direction you wish him to move.
Hear item sounds
When viewing collected items, press [Circle] to hear the sound made by that item when it is picked up. This is especially amusing with the people that are collected.
Cousins follow
Hold [Circle] and walk by any cousins to have them follow you. They will even go from screen to screen. You can get all cousins to follow you.
Original Katamari Damacy girl
In the 1000 Paper Cranes level, in one of the hallways is the little girl from the original Katamari Damacy. If your Katamari is big enough, bump into her to hear her say, "Oh, I feel it," which was one of her famous lines from when you restored a constellation in the game.
