I used joints extension to make a cauldron that can hold little pieces of meat and you can push or shoot the cauldron to make the meat fall out.

It has no practical purpose in the game and is pointless
You could try like a lava/acid type of approach with your cauldron idea. Maybe run into it and have it pour its contents for a puzzle perhaps. Pretty neat though.
