Real Super Powers

While I was going over some my old documents on abilities, I came across something: a neat little piece of information I wasn't aware of before.

It seems that kirbies (for those of you who don't know, that would be a person who can copy or absorb the ability of another) can't mimic abilities that GENERATE a type of substance. They can only mimic abilities that involve some type of manipulation. For instance, if a person has the ability to generate ooze from their hands or body, a mimic can't copy it. But, if a person has the ability to manipulate liquids, a kirby is capable of attaining that power.
Now, let's say a person is capable of generating AND manipulating a substance. I believe a kirby will only get the manipulation aspect of that ability, and not the generating aspect.

Understand? :)
