Some time ago, there was a thread (https://umd.net/groups/i/october-finds) mentioning the Belgian movie K3 Dierenhotel (2014) and the scene where Kristel Verbeke (and Winston Post) end up in a mud pit when trying to herd escaped sheep. Here is the mud scene in its entirety: https://ok.ru/video/2944699861552
It turns out there is another, short but nice, messy scene in that movie, where Jacques Vermeire tries to demonstrate a milking machine to Kristel Verbeke, but the machine explodes and splashes both with curdled milk: https://ok.ru/video/2944699927088
