For those wondering, the brown mucus is the chyme of mixed proteins, saliva, food, gastric secretions and partially digested carbohydrates and proteins from the stomach, also known as chyme.

I didn't know if there would be any stringy saliva in the small intestine, I couldn't find any evidence of such, but I could use a tapping technique to emulate the shine you would find evidential in the bowels from the saliva secretion found there and other mucosa~

I was assured by a friend that villi are microscopic and such depiction of the structure of the was taken from looking at real life endoscopy sources.

Questioning if I should really draw skeletons that flowed with the tsunami of digested food further in the bowels... I do digest, it's just Kobaan's metabolism is veeeery slow and hence his chonky physique.
