What does a snake's stool look like?

The sick snake has thin green feces. Normal snake stools are thin, dry and brown. Before the snake defecates, it climbs to the tree, ties a knot on the branch with its neck, and then ties a knot on its chest with its tail as tightly as possible (just like wearing a corset). Then, it held its breath, pulled the knot on its chest to its lower abdomen, and squeezed the excrement out of its stomach from its anus.
