Night-slugs have a humanoid structure with blotch-grey skin bearing randomly arranged tufts of muddy-brown hair. Their arms are thin and elongated, hanging limply at their sides, and they seem to possess little if any muscle tone in general. Their ligaments and tendons are exceptionally elastic, allowing a night-slug to elongate its arms and legs, in the process pulling what muscle it has closer to its frame. In addition, night-slugs have a “collapsible” skeleton; its bones are composed primarily of cartilage, allowing the creature to squeeze into incredibly small areas.
