Ok, there is one item I really want in XIII. The Growth Egg. It doubles CP after every battle.

My question is: Is there more than one way to get one?
I know that the Growth Egg is the reward for killing a Neochu in one of the Pulse Cie'th Stone missions. But, I don't want to fight a damn Neochu just yet.
The one in the Titan's Trials is giving me problems. I get it to half HP, then I get over whelmed by those little ball plant things. So annoying.

Having a Growth Egg would make farming for CP go by faster.
