Confused as to how to reach the bonus stages? Losing track of the Prince's wacky cousins? Wanna know where those presents are hidden at? Trying to figure out how to shoot eye lasers like the King? Check out this guide today, and let your mind roll up our tips so you can better aid the Prince in making the world a much, much weirder place.

Unlock The Memorial Option

Finish the game (by successfully completing the dog's solar system stage). This option includes a movie viewer and a music player.

Unlock Second Bonus Movie

To unlock the second bonus movie, complete the cousin collecting stage.

Unlock Staff Credits Stage

Finish the game, and then talk to the girl with the yellow shirt to play this stage again.

Unlock Comet Stage

Finish the game, and then talk to the astronaut to play this stage.

Unlock Million Roses Stage

Complete the cousin-collecting stage, and then talk to the rose to play this stage.

Hint: View Comets & Shooting Stars

After completing a standard stage with a high score, a comet will fly across the sky, and a button will be displayed. On the Cosmos Screen (which can be accessed by flying up into the sky from the hub screens), press the indicated button to see the comet fly across in the background.

Unlock Cousin Collecting Stage

Find all the cousins, and then talk to the boy with the yellow shirt to play this stage.

Unlockable Screens And Menus

Collect one million roses in the special stage to unlock an extra song as well as some new title screens.

Hint: Size Estimation

On the mission Just the Right Size, you have to guess what size your katamari will be. Move your katamari and place something substantial between the katamari and the camera to force the see-through portal view to appear. This portal view gives you an approximate guide to the ideal size of your katamari for that stage.

Hint: Roll Up the King and the Queen

In the bird and elephant stage, you will see the King wandering around. To roll him up, you must be approximately 3,100m. To roll up the Queen, you must have rolled up the King, and then, play the bird and elephant stage again and you can roll her up at about 2,700m. After that, you will see them in certain areas of different stages.
