I think those are usually referred to as "teapot platies" these days - basically, they're the platy equivalent of a balloon molly. They will breed true, if that's the case, since the compacted shape is due to a genetic defect. Whether or not such a fish is desirable is a matter of personal opinion - personally, I think they (and the balloon mollies, and those balloon rams) kinda look like they swam face-first into a brick wall and got smushed.
