Special Bubbles are collectibles in the game that don’t exactly give you any prize (unless you’re a trophy hunter, of course!). There’s five in every main story level excluding the final boss fight with the T-Rex and let’s just say - they aren’t intricately hidden. Simple curiosity could help you find most of these without a guide. Please check here for my mini-guide to locations to all the Special Bubbles.

This trophy is awarded when you earn fifteen of the twenty-five collectible Special Bubbles. If going in the correct order, this should unlock when you collect the final bubble for ‘Inside Big Rex’.

This can be the trophy that prevents players from gaining a perfect completion rate. If you have a motion controller and two Dualshock controllers, though, the problem can easily be addressed. Thankfully, DarkSeraphim666 has discovered an excellent exploit, in case you don’t have the required amount of controllers.

I posted this in response to another guy's thread but I figured I'd also make my own thread in case people are looking for a way to dodge gathering 8 zillion friends and/or controllers for this one trophy. I love doing as little work as possible.

"You can do it with 2 players and 1 of each controller (regular/Move).

As the Sackboy is flying up the esophagus, pause the game and change your controller settings 4 times and pick guest for each new Sackboy

If you do it fast enough all the new Sackboys will spawn at the finish screen and nobody will time out and disappear again. New Sackboys spawning at the end screen don't count as deaths because technically they never died.

This could have been avoided if they put a "no new Sackboys" gate at the beginning but its all local so it didn't matter.

If you happen to not be fast enough you can still get 1/2/3 more actual Dual shocks and follow same procedure. Just make sure all sack boys are signed in before you reach the end screen so they spawn there."

This trophy is awarded when you earn five of the twenty-five collectible Special Bubbles. If going in the correct order, this should unlock when you collect the final bubble for ‘Learning to Move’.

This race happens near the end of Hot Stepping. Specials Bubbles #4 and #5 are also available in the race, so I highly recommend collecting the Bubbles and speed running the race separately. Or, if you’d rather not have the hassle of going through the level again for the Bubbles, collect them after the race.

One of the races in the game which dawdling in is risky. Have the Move controller create platforms for Sackboy and jump to grab the fast-spinning handle in the middle when you reach the fourth step. Time it correctly so you land on the next level of the race. Here, have the Move controller create a pear-shaped handhold, and take a breather while Sackboy turns the circle. During this, the Move controller must create a platform again for the player, three to be exact. Grab another fast-spinning handle in the center and continue onward. Next, and this is the final section; have the Sackboy idle in the pink section of the spine bridge and have the Move controller catapult the player upwards to finally reach the goal. If 2800 points or more were still on the timer, the trophy will unlock soon afterwards.

The first race of the game in the first level of the game - I think you get the idea that it’ll be pretty easy. I get this without realizing when I first played the game, not even thinking of trophies at the time, and the time is pretty lenient, on top of that.

Immediately run right and have the Move controller pull the platform upwards for the Sackboy. Do the same on the opposite side when you arrive. Run forward again and have the Move controller press the pink button to have the Sackboy catapulted upwards. No time to relax yet - press the next button to the right to have the Sackboy pushed up a slippery slope. Run forward again and enter the circular-edged platform like from the beginning of the race. Pull upwards and enter another circular-edged platform directly from the last. Move towards the catapult again and thrust Sackboy into the air. Finally, press the catapult to the left to have Sackboy hurtling towards the finish line, and the level’s end. If 1000 points or more were still on the timer, the trophy will unlock soon afterwards.

Ace the second level of Prehistoric Moves; Prehistoric Paradise. Since the first level was just a tutorial, this level still pretty much holds your hand until the end. Here’s some areas and sections to be aware of:

- The first half of the level is pretty much danger-free. Nothing to worry about as there’s nothing difficult.

- When the sky blackens and a few cavemen mention about the falling meteorites, it’s time to become more cautious. The falling fire meteorites kill upon impact; so have the Move controller hold the shelter house over the player. Don’t hold it too close; should the player jump or rush forward they’d immediately run into the fire outer rim of the shelter house.

Ace the third level of Prehistoric Moves; Cro-Magnon City. This level changes notably in difficulty compared to the level before and you’ll most likely need to replay at least once - unless you’re really lucky. Here’s some areas and sections to be aware of:

- The ragged platforms at the beginning and middle of the level can be killer if you’re not careful. At first you only need to make sure you don’t slip up and pull the platform away, catapulting the Sackboy. Next time you need to worry about flame pounders on top of that.

- Don’t worry about the animal rides during the level; as long as you stay in the carriage no harm comes your way.

- All areas besides those mentioned are relatively straight-forward and for the most part harmless.

Ace the final level of Prehistoric Moves; Fossil Fight. This is the final boss battle of the game and in fact proves no difficulty whatsoever; the T-Rex attacks scarcely and infrequently. I got the ace in when I first played this level - and got it first try. Here’s some parts of the boss fight you should be made aware of:

- When the T-Rex approaches, have to Move controller catapult the Sackboy upwards and grab onto the sponge part of the monster’s tail. The T-Rex will roar and this is the opening to drop the objects into its mouth. Do this three to four times to move onto the next part of the battle.

- It gets even easier here. All that’s required now is to catapult into the air again and hit the weak spot on top of its head. Do this two or three times and the T-Rex will fall for good. Simply run to the scoreboard and the battle is over! Simple as that!

Key Location: In Prehistoric Paradise, after using two spine bridges in a row, there’ll be a key visible in a high-up cubby-hole and a skull nearby. Have the Move controller pull the skull tongue as Sackboy sits on top to catapult upwards and grab the key.

Sackboy will be sitting on two dinosaur heads and the Move controller has the responsibility of shooting cages up above. Some hold score bubbles while others hold fire logs. Over the process of the mini-game more and more fire cages appear and pretty soon the sky is clogged with cages of all sorts, left, right and center. To make matters worse, ever so often the dinosaur heads rise upwards, making for two possible hazards - one, where you can be squashed into the fire cages, and two, where a traffic of the cages causes them to burst, and the logs come tumbling down the dinosaur nose towards you. Make sure you keep the score multiplier high, and keep complete focus.
 

Key Location: Near the beginning of the Inside Big Rex, you’ll have to jump left to right from pink platforms. On the second set, jump to the left instead of the main path leading to the right, and the key is waiting.

This was the easiest of the selection. The Move controller takes control of the glowing beetle which he wave around at his dispense; this is used for destroying incoming obstacles and helping the Sackboy catapult towards the score bubbles, which are falling through a chute at top speed. At intervals, a spherical object will hang from the middle of the chute, enabling Sackboy to grab on and attain a LOT of bubbles and a multiplier of up to 7x. Use this to your advantage. I recommend aiming for the middle of the chute; it gives you the most bubbles while you jump at it.

Key Location: Near the beginning of the Cro-Magnon City, you’ll come to a part where you must climb up to a wooden hut where you’ll begin your ride on the dinosaur. Instead, jump on the towering stone pillars to the right of it and catapult yourself up to the key above.

This can be tough. Sackboy will sit in a basket carried by the Move controller and must collect bubbles along the way. It works in a kind of side-scroller pattern. It gets progressively harder as there will be random islands of fire as well as small islands with score bubbles. Make sure not to jerk the Move controller too much; you might buckle Sackboy out of the basket. Once you get into the flow of how the system is, and after a few practice runs, you should then get the required score and the trophy along with it.

Key Location: In Hot Stepping, when the lava rises and you must create platforms to swiftly escape, there will be a crossroads near the end. Choosing the left gets you out, but going right grants you access to the final Challenge key.

This is a simple, but fun and addictive mini-game. Platforms will move downwards. The Move controller must press the outline behind them to make the Platforms appear, and three bubbles will be dropped when it is. The Sackboys can collect bubbles, and the speed of the downward platforms will eventually hasten. More platforms, more points. Every so often a creature will move upward on the screen holding a bonus of five or six bubbles; make sure to grab these as extra.
