Enter the debug code at the main menu: Up, up, down, down, left, right, left, right, O, X Hold R1 in the debug menu to automatically gain kills. (You'll want to raise it to 1000) Next, unlock all dragons and unlock all levels with each dragon. After you've done that, go to any level in the game. I'd recommend TA 13 as you can jump into the spikes below the spawn point. Finally, go to the training mode. (The large dragon picture to the right of the level selection) - You'll want to enter training mode with all dragons. The first one you'll need to bounce on the right AI dragon 25 times or until it drops down and make the left AI dragon float in the air for 7 seconds. Then enter and exit the training mode with all other dragons. Once you've done all of those steps, you'll earn all 60 trophies including the platinum!
