Katamari Damacy REROLL

The last achievement in Katamari Damacy REROLL involves picking up one of every item/creature/person/cousin. In order for any pickups to count you have to "successfully" complete a level, that means: getting to the size required for "Make a Star" levels and then quitting, quitting anytime on Eternal levels, or fully finishing constellation levels.

Easiest way to do this is to follow a google spreadsheet:

(This first tab emulates the in-game 100% object booklet, so you can line it up and find what you are missing, the second tab is a list for all items you can get level-by-level.)

My recommendation is that you first play through the game normally and simply try your best to grab everything you can notice naturally - then start using this guide to find the few final missing items that are giving you trouble.
