A couple of examples of 2.5 with wet mud. Having been in this kind of mud plenty of times, I can say the mud moves very realistically, and in the second clip, you can see how the mud sticks (also realistically) too. Both of these clips were from a starting image rather than text to video.

It's the only AI that I've tried so far that will do wet mud this realistically.
I am still trying to find out an effective prompt for sink unders, where you start to face upwards before going under the mud when the mud reaches your chin. Most of the time it has you facing up when you're still only chest deep.
