Raising Aptitude
When you degenerate a Digimon, Aptitude is added to it. This raises the level limit of the given Digimon that was degenerated, although the level limit raising fluctuates based on the Digimon type. This will allow you to level-up your Digimon to higher levels, thus making them much more powerful.

Easter Egg: Silent Digimon
From time to time, on the top screen of your DS, a Digimon will talk about any given item in your farm. However, sometimes they appear on-screen to say something, but end up saying nothing at all. A glitch, perhaps?
