Beautiful Katamari

to get this you have to dash 30 times in one stage.

to dash move both thumb sticks back and forward untill the katamari starts to spin, let go of the sticks and the the katamari will dash forwards.

you can easy get this in time trial or eternal mode and just keep on dashing into a wall or anything you want :)

For this achievement, you have to dash 30 times in a single stage. This is done by moving the sticks back and forth in alternating directions.

I would advise doing this once you have unlocked the eternal mode for a level. To unlock the eternal mode, score over 100 points in that level. After you have dashed 30 times, you can exit the level by pressing X.

If you want to be extra efficient, you can do this achievement while earning this one (crash into a wall 30 times in one level):

This Can be done in the Chateau' Notre Desir. This is the level where you re-roll Uranus with no time limit. Just wait until after they stop asking for memories and do the 30 dashes ( move both thumb sticks back and forward untill the katamari starts to spin ) and press X to end the level. The achievement will pop after you get all your presents and cousins.
