Deep-sea creatures of Aquamantis that contain the highly coveted element called the Pearl which happens to be the Smartian’s pituitary glands.
Because of the Heavy Water and the depths of which the Smartian’s live, their pituitary glands are densely concentrated Heavy-DTM which is an incredibly powerful hallucinogen.
These Pearls are the primary active ingredient in Dr. HYM’s Hallucination Engine. Smartian’s are the carriers that make them critical for Dr. HYM’s efforts to re-colonize the universe using his experimental device.
