Well, for relatively minor changes/zaps, the 'excess' mass is easily attainable, though the science of the 'relocation' and 'transformation' of it would still be problematic without relying on 'black box' technologies.
For the demon exampe, horns and wings and tails are all relatively minor enough that mass can come from things like a meal in the stomach/bowels, becoming a little trimmer/thinner, or even gaining hollow bones, the way regular avians have. And because the relation between height and weight( or mass) is not linear, the loss of a few inches of height can provide a fair amount of 'freed-up' mass to use for other things. For relatively minor additions of mass, the requisites could be 'harvested' from the surroundings (air, polution in the air, the ground, heck even clothing).
Of course, the matter of zappy is a little more complicated than taking mass from one area and converting it to a different sort of matter. ^^;
Now, something like a centaur would require a lot more mass than one would generlly consider available from the methods mentioned above. (Unless, of course, it was a /significant/ loss of height, making for a cute minature centaur), but if you start tweaking in magic (or sufficiently advanced technology, thank you Mr. Clarke) you could, for instance, take the mass from a more remote location, maybe with a centaur taking an actual horse from somewhere and doing a merge, not a full transform, with the excess matter being converted into energy to help power it). That is, a combination of matter transferance as well as manipulation.
Of course, there's another way to get matter from 'nothing' while still within the confines of current accepted scientific understanding. The old formula E=mc^2 can be rewritten in terms of m, that is, energy can be changed into matter. Granted, it takes a whole lot of energy to create a small bit of matter, but if you ignore the difficulties of harvesting, channeling, and transforming the energy into matter, one can - in essence - appear to create something out of nothing.
The specifics of the mechanism(s) I'm using will have to remain vague for now, but shall be revealed in due course. ^.~
A minor point of interest though, the reported incidents: mermaid, demon, centaur are chronologicly in increasing order of 'difficulty' with consideration to the question of mass/matter (approx two weeks separating each). Could someone be working up to something 'bigger'?
As for the presence or absence of governmental conspiracies or coverups, I have to temporarily fall back to a comment with its origins in the intel community: "I can neither confirm nor deny..." To do otherwise would be spoilers, yanno? ^.~
