Leave game on idle in the end of credits for 30 minutes.
This one is actually really easy, as long as you're aware of it.
For a sure fire way to get this trophy, bring up the XMB when you're presented with the first depth of credits. Although you don't need to do this, it's the best way. If the XMB is not up, your organism might accidentally consume the first credit food and advance to the next level. The reason being, because your creature will float around by itself on idle. So just bring up the XMB, and come back in 32 minutes; just to be safe. There's no need to worry about controller time-out times, as the trophy will still unlock, even if you're controller turns off during the wait time
Complete any campaign without being hurt.
One of the easier trophies in the game. Just make sure not to be hit by any advanced life forms and this trophy is yours. When proceeding to the next depth, just be sure to immediately go for the red marker that advances you.
Complete any campaign without eating anything.
This one can actually be a pain, and is partly luck.
The only thing that you're able to consume is the campaign completion egg. Which can be a pain considering that the egg is surrounded by food. The best advice I can give you is to use the final organism (the one that has a protective shell when holding a controller button).
Whenever you're surrounded by food, or advanced creatures; hold a controller button, then let go in order to push them away. Keep the shell closed, and do not open it up until you're close to the red gate to proceed to the next depth. The hardest part of this trophy is actually consuming the campaign completion egg without eating any of the food surrounding it. In order to that, use the same concept I just mentioned, but be EXTRA careful. Opening your shell too early, or too late will cause you to consume any surrounding food. Make sure all food is away before consuming the campaign completion egg.
Complete any campaign within 120 seconds.
Another fairly easy trophy. Although you're able to actually achieve this with any of the organisms, I would recommend waiting until you become the "Fish Shaped" creature. The reason I recommend waiting, is because this creature is he fastest. It's special ability is speed when holding a button on the controller. It makes this trophy much easier, because sometimes you will miss the red gates, or won't be able to find them right away. This organisms speed eliminates most of those problems.
Just be sure to reach the final depth, and consume the campaign egg within 120 seconds in order to get this trophy.
Start the first campaign after installing.
This one is pretty self-explanatory. Just start the game, and start your first campaign after installing the trophy patch. If you've already unlocked multiple campaigns before the trophy patch went live, you can select any campaign, and this trophy will unlock.
Complete any campaign with 4 players.
*Requires four controllers.
This trophy is actually easier than it would seem. Instead of actually playing through the entire campaign with four players, you're able to activate the controllers right before consuming the campaign egg.
To easily obtain this trophy, proceed to the depth with the campaign completion egg. Once your there, before consuming the egg; bring up the XMB and activate all four controllers. After activating all controllers, you should notice upon returning to the game, that there are now four organisms on the screen. Once you see that, consume the campaign egg with the controller you proceeded to this depth with.
Complete any campaign with a creature of 25 segments or longer.
Another simple trophy. This trophy is attainable on any campaign, however I'd avoid doing it on the first one as it's a bit harder on that one. Basically all you need to do is consume all of the advanced life forms, as well as the food on each depth. Since this trophy states that you must clear a campaign in order to unlock the trophy, you must eat the campaign completion egg. The trophy will pop up once the campaign egg is consumed, so be sure not to miss any advanced life forms or food, so you do not miss the trophy.
Decorate your creature with more than 10 alternating segments.
This one can be tricky if you're no familiar with how to evolve your creature. But once you read this guide, you should get the hang of it. Basically, segments are added to your creature, based on the food you consume. So, if you were to eat one or two pieces of food, you would gain another segment. However, these segments are not considered locked in (Filled out) until you consume a red gem from an advanced life form. So, say for example you consume one piece of food and add a segment to your creature, now when you consume a red gem from an advanced life form that segment that was just added will receive a pair of wings, or fancy decoration. Now consume another piece of food, and notice that another segment has been added. DO NOT add wings or decoration to this segment. What you want to do is consume another piece of food to add a third segment, now on this third segment, lock it in by eating another red gem. By now, your creature should look something similar to this (Wings, plain segment, wings). You want to repeat this process in until you have a creature that has 10 alternating segments. This trophy will unlock once you have 10 alternating segments. You do not need to complete the campaign in order to unlock this trophy.
Eat all foods in a campaign without killing any advanced creature.
Just be sure to not consume any advanced creatures and this trophy is yours! Use the creature that has the paralyzing special, so once an advanced creature comes close, you can hold a button on the controller and paralyze them. Be sure do be a decent distance away before letting go of the button, to be sure not to accidentally kill the creature. If you accidentally consume a piece of a creature, don't fret! As long as the creature does not die, you'll still be able to earn this trophy. One other thing that you should watch out for while going for this trophy are creatures that produce food. It's easy to bypass these creatures, and miss the trophy. Instead, wait for a minute on each depth after consuming all the food to insure that no other food will appear.
Eat all advanced creatures in a campaign without eating any food.
I know there are a lot of people who claim this trophy is tough, but I found it to be quite easy. What you want to do is use the creature that has the paralyzing special. Whenever you're near food on a specific depth, hold a button on the controller for your creature to turn yellow, as it will not consume any food in this state. On top of that, any food that comes into contact with your creature turns yellow and will paralyze any creature that consumes it, thus making this trophy a little easier to obtain, as you won't have t chase down fast moving creatures. This trophy will unlock once you reach the final depth. You do not need to consume the campaign completion egg, which actually makes this trophy potentially more easy, as you won't have to avoid all the food that surrounds the egg. Just be sure to eat the creatures on the final depth.
Consume all credit foods.
For this trophy, you need to consume all of the food that appears next to the credit names at each depth. Be sure to double check each depth before proceeding, because once you advance, there is no way to return to the previous depth. This is a missable trophy if you're not careful.
Paralyse the same creature 5 times without killing it.
You'll want to wait until you're playing the campaign for the creature with yellow hooks, that turns completely yellow when you press a button on the controller.
To get this trophy, simply press any button on the controller when an advanced life form is near you, to paralyze it. Continue to paralyze the same creature five times without killing it. Just make sure you do not consume all segments of the creature you're paralyzing. Also, you do not need to paralyze the creature five times consecutively, only five times before advancing to the next depth, or the count starts over.
Take more than 10 screenshots.
*This trophy requires the flOw expansion pack.
In order to get this trophy, you need to consume the life forms which look like cameras. Or to put it more appropriately, the creatures that have a circle in the middle with an S on each side.
Eat every level complete egg.
This one is actually very simple. Just complete every campaign within the game, consuming all the campaign completion eggs.
