Crash Of The Titans

I have found an awesome way to get lives very fast which will help you greatly in trying to beat the harder levels later on in the game (Mainly for hard play through) or for getting this achievement.

First of all you need to have reached level 3 "A Zero's Journey" Then reply this episode, Follow the path down past the four walls that are trying to push you over the cliff, Jump up the cliff and grab the free jack (Gold thing) then jump across the cliff and jack the Snipe.

Now, run past next two moving walls(Make sure you do not get pushed off here otherwise you will lose your Snipe).

Next press the B button on the big blue ball, This will give you the chance of getting a free life(The golden apples) And a bunch of Mojo which will also score free lives if you collect enough.

Now jump up the cliff and jack the next monster run past all the little enemy that will start to spawn and across the bridge, you will see a second big blue ball which will get you even more life's or mojo.

Now pause the game and hit "Save and Exit" Rinse and repeat. This is much easier and faster than playing the first level over and over again.

If you find this solution to be unhelpful, please tell me why in a comment and I will update it the next time I'm online.

On Episode 10, when you reach the weird scientist's tower-thingy, you'll be forced to jack a Sludge to jack the Scorporilla in the center of the room. When you are that Scorporilla, you can run around and kill the spawning Sludges (that won't stop respawning until you destroy all the metal machines). Keep killing these until you get enough of those weird experience bubbles to give you enough lives to get the achievement. (It took me about a half-hour, but I got the "Where Did All The Time Go?" achievement on top of that.)

Ok by far the easiest way to make tons of lives, the just 15 lives needed for achievement or if you want to make some extra for any other level that is been hard for you to pass.
Requirement: need to pass the Mojo Room on level 6 at least once.
Mojo Room #6 On a Roller!
Mission: Defeat all enemies before time runs out
Time: 80 seconds
I have tried all the other 19 mojo rooms to compare which one is the easiest and more effective.

This Mojo Room is pretty easy because it only brings 3 Rhinorollers. Just jack the first one and head for the other 2 without hesitation.
Now the peculiar trick in this that most of the time at least one of the Rhinos have (2x) big mojo bubble and then head fast for the barrels to make lots of mojo and right away direct your rolling Rhino to the super Big Mojo Container on the right that it is only opened with the destruction of a Titan. Note that I always would leave the minions for last since their amount of mojo is not that considerable. The great news is that this Big Mojo Container also includes a Golden Apple which means an extra live. This doesn’t happen all the time as well as in the other solutions posted here. I have tried all of them and the Golden Apple doesn’t appear every time, I played all the game on hard maybe that might be the reason that it doesn’t repeat every time. Now I have notice and tried to make a lot of sense of the combination that make that apple appear most repeatedly because there is two kinds of Rhinorollers a dark and a golden one sometimes it comes in 3 of a same kind and sometimes combined 2 to 1. I didn’t needed more than 20 lives for the last 4 episodes. Then you rinse and save automatically getting out of the mojo room and repeat getting back in the same place. The best part of all is that time in the mojo room will be much less than the 80 seconds that it last to accomplished it so for the achievement it will be a really fast and easy way to get the 15 lives here. Good luck and have fun.
