i'm working on a shot here at work of a T-rex standing in snow and turning around and leaving the frame. he scratches up a bunch of snow and dirt. they did a bunch of particle interactions for the snow and dirt in Houdini. It looks just like your dirt that comes out of the pot, ar Lutik, only a different color.
it just made me think of your shot, thats all. i mentioned that the way your dirt moved made it look like cocoa pebbles. theirs does here, too.
