There is a plug-in for Maya, Blastcode http://www.blastcode.com/
You may have luck using that (or something alike for XSI) to generate
chunks of the sandcastle breaking off, then take those chunks, smooth
and/or relax them while they´re emitting themselves into particleblobs
and have those dissolve into extinction?
Never used blastcode sofar...

You might get some mileage out of the smooth or relax deform but in the end
you'll probably end up using a mixture of shape, lattice and cage. Or
something.

Sascha,
Just curious but what is the scenario? Is it waves hitting the castle
or is the sand castle under still water like in a tank? Sounds like the
real sell would be in the clumps animating off if Marc's solution is
right for the scenario.

Maya and Houdini would be also available.
