This is for beating the game basically. Complete all the levels under RoboKing and King of all Cosmos. Most levels are very simple and in reality very hard to actually fail. There is one level under King where you have to heat up your Katamari to 10,000C and that one is a little annoying but overall progressing through the levels are simple and should take you no less then 4 to 5 hours.

This could be your best friend or worst enemy, and will probably be the last trophy you earn. You must collect everything there is to be collected. Roll and pick up whatever is possible to pick up.
If you play through the game and beat regurlar, katamari drive, eternal, and classic modes, then at this point you should have 90% of your collection done, and you might be lucky and have it completed by then if you were lucky enough to just happen to roll over everything. There isn't much that can be done here, if you roll up an item and go to your collection page it doesen't tell you where you found it, making it harder for a community to get around this but for some reference try visiting HERE and HERE.

Throughout your playthrough you will roll up some cousins, basically more playable characters after you have found them and rolled them up. For every level in the bottom right hand side of the screen there are little icons that show how many cousins are in there, and if you have found them or not, saving you some time. If you want locations for the cousins within the levels please visit HERE.

Throughout your playthrough you might find some Royal Presents, little decorations for your character to wear. Presents are harder to find than cousins, and like cousins, you can see how many you are missing or have in a certain level by looking in the bottom right hand side of the screen and looking at the icons. For locations of the presents within a level please visit HERE.

This may take some time. The level you will be doing this on and is only possible on is "Wake up the King!" under the King's levels. When you first complete this level you can really only max out the Katamari at around 1,750,000km. First you will want to go through all the possible levels on Katamari Drive, Eternal, and Classic mode. For more on those modes please see "Katamari Speedster", "Forever a traveler", and "Back Then".
Second, after going through all those possible levels, and making a few stardust Katamari's here and there, head back to this level and play it on Eternal, so you don't get the time restriction or accidentally roll up the King at the end which ends the level. Now you should have made enough stars and stardust in the cosmos to roll all of them up until you reach that 2,000,000km. If you can't yet do it, go to any level and play it on eternal and make more stardust until you can reach it, but you should have enough by the time you beat all possible modes on all possible levels.

This may be one of the tougher/more luck based trophies in the game. Whenever you fail to do a request for the King or RoboKing, you will be brought to a little mini game where you are being punished and must avoid erupting rocks. To gain points you must just survive, over time your points add up faster but the rocks release faster. The best strategy for this is to just move the prince/cousin to the very right side of the screen, you can avoid the rocks more then half the time and every so often have to move your character to the left to avoid alittle bit. Rememeber you can only take 3 hits but if you're hit early on don't worry as it is easier to evade when you're hit 2 times. In fact I encourage you to hit yourself twice early on because if you're hit later your points slow down and don't add up as fast. If you want a fast level to quickly fail on to be brought to the mini game, try the Campfire level and burnout your Katamari in the river, or the 10,000C level and run into ice cream to burn out.

This is very easy, when you beat the game the first time and are taken to the credits you will be able to play a mini game called 8 bit Katamari where you bounce a Katamari on a cloud and pick stuff up in the air, and you lose the game if you fall off the cloud. Be very careful, you have more then enough time to get 100,000 points if you don't fall. So just bounce up, pick up stuff in the air and 50,000 will come easily, and remember if you tap X you can slowly float downwards if you're going too fast thinking you might miss the cloud.

Simply go to a level under King of all Cosmos (not RoboKing) and play a level in any mode you want that you have already completed, and when you finish the level you will be asked if you want to overwrite your star or make stardust, choose stardust for the trophy.

Just complete the tutorial of the game, it is the first level you will play upon start up.

This will come over time during your entire playthrough, for more in depth locations please see "Completist"

This will come over time during your entire playthrough, for more in depth locations please see "Present Collector"

This can be done alone as long as you have the second controller. Go to VS Battle/Co-op mode in village square and play a battle level, simply play one controller until it is larger then player two and let them sit to win easily, then repeat this 29 more times.

This is best done on an eternal level, so go to any level you have unlocked eternal on, start it up and pick up a lot of stuff, and then go to a wall, or moving object that is bigger then you and let yourself get hit or speed into the wall. This will break apart your Katamari, keep doing so until you have broken it at least 50 times, and then hit sqaure to stop rolling and return to village square for the trophy.

This is pretty much unmissable if you complete all the requests. You will earn this on any level that requires you to roll up to atleast 1Km starting from meters.

There are four mini games in total.

The ending mini game-beat the game once
Beautiful Katamari Normal-Beat the game on Katamari Drive mode
Beautiful Katamari Hard-Beat the game on Katamari Drive mode
Roll up the fans mini game-Finish all classic levels

For more on the modes Katamari Drive and Classic see "Katamari Speedster" and "Back Then"

You start the game with 3 songs in your Katamari Collection so you will want to go and play a few levels first and then you can go back to Katamari Collection later and you will easily have every new song you encountered, simply play 5 of them, you don't even have to listen to the whole song, then exit for the trophy.
