Facts about turds....

Human turds varies significantly in appearance, depending on diet and health. Normally it is semisolid, with a mucus coating. The brown coloration comes from a combination of bile and bilirubin, which comes from dead red blood cells.
The perceived bad odor of a turd has been hypothesized to be a deterrent for humans, as consuming or touching it may result in sickness or infection. Human perception of the odor may be contrasted by a non-human animal's perception of it; for example, an animal who eats turds may be attracted to its odor.
