What steps would you use to create an animated liquid forming from a swirl into a final object form?

Hi all

Just curious as to the workflow and steps you would take if you had to create the following effect? -

* I need to create chocolate in a liquid form that is swirling around in mid-air (almost like a long thin tail) before eventually forming (by pouring into...) a final solid object? *

I was thinking to go about it by creating a thin swirling "shell" in C4D (though not completely sure yet how to? maybe an extruded spline?) then (if I have to) gutting this shell so there are no polygons inside and exporting it into Realflow and filling it as a liquid? But after that I'm not sure how best to get the now liquified shell to transform into a final object form that in this case is meant to represent an animal model.

any suggestions tips would be really appreciated.
