A Fish?

You turn back to find that a simple blue fish has gripped your foot with its large bass-like mouth. You let out a small chuckle as you kick the fish off and continue onward, barefoot through the swamp, relieved at the realisation the noise was only the chasing of a fish.

You keep moving through the revolting waters, feeling mud and filth passing between your toes with every step, sludge collecting to your shins as you move forward in the murky shallows. Eventually, somewhere in the hazy yellowish brown mist, you spot something a few feet ahead of you. A building or maybe a structure? It's too far away to see exactly what it is, the prosice details and size masked by the thick swamp air. You keep moving on for a few minutes until you are just about right next to it, bringing it well within sight without abstruction.
