Considering the means of cloning exist in even my world, if only through the means of magic, I'm sure it wouldn't take much for such things to exist in other worlds through technology. Replication of food would be interesting.

But I may be approaching such things in a strange way. We just don't know what the Malnosso have had available to them, in terms of technology or information. [Just because they didn't know a lot doesn't mean the Malnosso were in the exact same situation.]
