This video is a slow, vertical sink, in bubbly swamp mud. There is no backstory. Doug spins around a couple of times to show that he is vertical in the mud. The mud gets thicker as Doug goes deeper, but there seems to be no bottom. This video features some struggling. It does not end in total immersion. Doug stops sinking when he is up to his ears. After that, you see the extrication process. Doug demonstrates how to get out of deep mud. This clip is offered in Quicktime format with a 960x540 frame size. The video and audio are both good quality.
