Katamari Damacy

To unlock a comet you have to beat each level under a specific time limit.

Look for a television on Eternal #1. If you get close enough to it, you'll see yourself as you roll along the screen.

When you get pushed through the floor by a moving object such as the swing with bears on it on Make A Star 4, The King will warp you to another area of the level for your safety and give a short speech about the Royal Warp.

After completing the moon, do the stage again and make the moon into stardust. This gives you a movie of the little boy saying how rich people are different.

When you collect at least one of every object in the game, thus completing the Collection, the King of All Cosmos will give his praise as well as more balloons to carry the Prince on the Collection Menu.

After beating your friend in Space Mushroom, press triangle while the King Of All Cosmos is talking, to drop washpans on their head.

When you start a stage, the King will say "sending things to earth......" when he does that, open the disc tray and do not close it (or close it without the disc) and you will hear more things the king is sending to earth. They are pretty funny. When you are finished, just close the tray/ put in the game disc.
