This dude wandered through a forest where the floor was covered in mushrooms and the leaves were so thick he had to just keep walking forward with his hands in front of him. Then his legs disappeared. And then his torso. He kept wading but even if he went back the way he came it seems like the ground was giving way deeper and deeper. As if the forest had just opened up its maw and wanted him.
His clothes kept getting heavier the more crap they accumulated so he took them all off. This was a mistake because he immediately sunk down to his nipples and slowly to his shoulders almost immediately. Now he's struggling but he knows he's not going to die. The swamp is somehow telling him that he'll live through this. But what he doesn't know is he will only be part of this disgusting bubbling blob that rests in this depression in the forest. The bog has consumed him he just doesn't know it yet. Every inch of his body is going to be rubbed and kneaded until there's nothing left except a moaning neanderthal and a bubbling bog.
