【Brief Introduction】
PUPU has a peculiar appearance, serving as the planet's scavenger. With a vacuum-like mouth, it consumes substances from the ground and never experiences indigestion. PUPU is small in size, with a relatively short lifespan, making it a species with a brief yet active lifecycle.
Body Structure
① 【Eyes】
PUPU's eyes, situated on its head's top, consist of muscles, nerves, and eyeballs. They can swing and rotate widely, causing changes in PUPU's visual perception as the eyeballs move.
② 【Hands】
PUPU's small hands can not only pick up lightweight objects but also cooperate with other body organs for defense when it encounters danger.
③ 【Mouth】
PUPU's mouth seldom leaves the ground, resembling a large plunger. Without teeth, it can generate immense suction to draw objects from the surface into its body.
④ 【Ducts】
Ducts are vital organs inside PUPU, primarily responsible for transporting various substances within the body. Each duct has a distinct area of responsibility.
⑤ 【Vent】
The multiple vents on PUPU's back serve as crucial organs for metabolism, primarily expelling internal odors. Simultaneously, the metabolism helps mark its traveled route.
⑥ 【Legs】
PUPU's segmented legs consist of sturdy exoskeletal tissue, with numerous small jet orifices at the joints. In emergencies, it can release a large amount of toxic gas from these openings.
Life Overview
PUPU mostly inhabits deserts or barren terrains, where the vast and flat landscape minimizes the risk of sudden predator attacks for the not-so-swift PUPU. Picky eaters, PUPU solely relies on ground-based food. With its innate powerful digestive system, it can devour everything along its path. Inside PUPU's body acts as a natural chemical factory, categorizing ingested substances. Some are absorbed, while others fuse to create "defense weapons." Leveraging this ability, seemingly fragile PUPU often surprises adversaries and manages to escape successfully in perilous situations.
Gas Master
When PUPU is on the move, it releases a substantial amount of gas, known as "scent gas," which serves as a behavior marker recognizable only by its kind. As PUPU lacks territorial concepts and belongs to a nomadic group, leaving these markers along its route helps avoid encounters with fellow PUPUs. Since the places PUPU traverses remain devoid of food for an extended period, this behavior is a considerate gesture towards its counterparts.
The scent gas expelled from the vents on its back can disperse over a considerable distance with the airflow. In reality, these gases are the result of the daily ingested food within PUPU being converted into gas. Depending on the food type, the scent gas may appear colorless or colored. Each PUPU emits a unique scent gas, a secret known only to other PUPUs.
Open to All
Most of the time, PUPU's mouth adheres closely to the ground. Due to the absence of bones, the flexible mouth tissues can adapt to various terrains. Despite the outward calmness, the interior of the mouth continually employs suction to draw in anything movable from the ground. By coordinating the rhythm of leg movements to adjust suction strength and the muscular actions of the mouth, PUPU achieves unhindered mobility
The pliable oral cavity can accommodate objects larger than the esophagus, allowing the ingestion of large plant fruits or stones..
Poisonous Expert
【Displacement】
Displacement is the primary defense mechanism PUPU employs when facing danger. On both sides of PUPU's neck, unique organs called "ejection tubes" grow, expelling capsule-like projectiles produced internally. The exit of these ejection tubes is conveniently located just above its hands. The discharged projectiles are caught by the hands and thrown towards oncoming threats.
PUPU's varied diet results in the generation of numerous harmful substances during digestion. These substances, broken down by strong acids, produce toxic gases utilized within the intricate digestive system. This becomes a unique defensive weapon against adversaries during critical moments. For PUPU, not known for its speed, avoiding danger through agility is challenging. Hence, PUPU's defense strategy revolves around "displacement" and "defense."
【Defense】
When projectile defense fails, PUPU resorts to the ultimate measure—defense. It releases an abundance of toxic gas through the leg vents, creating a deadly barrier. The gas induces symptoms similar to the projectiles but on a larger scale, making it harder for other creatures to approach. After releasing the gas, PUPU consumes large amounts of food, making it vulnerable during this period.
Projectile Structure
The "projectile" PUPU uses for defense is a capsule synthesized in the specialized organ "ammunition chamber," where sticky impurities and harmful gases produced during digestion are processed. It takes the form of a hollow sphere enveloped in a gelatinous substance, providing strong flexibility but incapable of withstanding impact. Once thrown to the ground, the impact causes surface damage, releasing the toxic gas within into the air.
The surface of the projectile is semi-transparent, resistant to squeezing but highly vulnerable to impact. The milky-white elastic tissue wrapped around the surface naturally contracts, intensifying the release of toxic gas upon surface rupture. The gas has an extremely high concentration and blends well with the air.
Projectile Effects
The gas in the projectiles isn't lethal but is potent enough to deter most adversaries. Depending on the digested food, the poisoning effects can be categorized into three main types (demonstrated using a hypothetical creature called MOKAKA, which is actually no threat to PUPU):
【Olfactory Disturbance】
【Adverse Reactions】
【Muscle Paralysis】
An irritant gas causing temporary loss of smell or a strong sense of unpleasant odor.
Chemical toxins inducing adverse reactions in organisms, leading to symptoms like nausea, fever, and diarrhea.
Neurotoxins causing muscle paralysis, resulting in temporary full-body paralysis or weakness, with severe cases leading to incontinence.
Body Workshop
PUPU boasts one of the most advanced digestive systems among KAKA's creatures, featuring both a "primary digestive system" and "auxiliary digestive system."
【primary digestive system】
【auxiliary digestive system】
PUPU lacks dedicated excretory organs (such as urethra or anus). Daily excretion occurs by vaporizing food and expelling it through the upper exhaust pipe. Though these gases might sometimes contain pigments, they pose no harm to the natural environment.
Primary Digestive System
The primary digestive system comprises the inhalation tube, ingestion duct, stone sac, stomach, intestines, nutrient processor, waste gas duct, gas processor, lungs, and upper exhaust pipe, primarily responsible for intake, digestion, absorption, transportation, and excretion.
【Ingestion Duct】
The ingestion duct is a soft tissue segment from the mouth to the stone sac, a crucial organ responsible for transporting external food into the body.
【Inhalation Tube】
The inhalation tube pulls in air, generating suction that draws objects into the ingestion duct. Once inside, peristaltic motion in the ingestion duct muscles guides objects into the body.
【Stone Sac】
In PUPU's neck, the stone sac with small stones contracts and pulsates, crushing food from the ingestion duct. This readies the food for digestion before entering the stomach.
【Nutrient Processor】
The nutrient processor further decomposes the nutrients sent out by the stomach, converting them into essential nourishment and storing excess nutrients for future use.
【Waste Gas Duct】
A duct responsible for transporting harmless waste gas produced in the stomach to the gas processor.
【Stomach】
PUPU's potent stomach acid dissolves food, creating nutrients, harmless waste gas, harmful toxic gas, and sticky impurities. These are sent to other organs for further processing.
【Intestines】
The intestines, the longest duct in PUPU's body, transport nutrients to organs such as the bloodstream, muscles, and nervous tissues that sustain the body's functions.
【Gas Processor】
The gas processor blends harmless waste gas with internal chemicals, creating scented gas with markers only detectable by PUPU.
【Lungs】
PUPU's lungs store scented gas from processed food, serving as backup air in scarcity and emitted with abundant food.
【Upper Exhaust Pipe】
The upper exhaust pipe is used to expel excess scented gas from the lungs to the external environment.
Auxiliary Digestive System
The auxiliary digestive system in PUPU comprises unique organs—poison duct, bullet-making body, bullet delivery duct, pump, gas drum, and lower exhaust duct. It processes toxins and impurities the body can't absorb into various protective projectiles.
【Poison Duct】
A conduit that transports harmful gases produced in the stomach to the pump.
【Pump】
PUPU's pump dirty distributes and stores harmful gas from the stomach, directing it to the bullet-making body or gas drum as needed.
【Bullet Maker】
Connected to the stomach and pump, it processes sticky impurities from the stomach and harmful gases from the pump into various projectiles.
【Bullet Delivery Duct】
A conduit responsible for transporting completed projectiles out of the body.
【Gas Drum】
In PUPU's leg midsection, the collapsible gas drum swiftly expels gas through the lower exhaust duct for self-defense in times of danger.
【Lower Exhaust Duct】
Releases toxic gases creating a temporary "toxic barrier" for PUPU's self-defense.
Bullet Production Line
The bullet processor connects PUPU's stomach and pump organ, processing sticky impurities and harmful toxic gas as follows:
【Step1】
【Step2】
Introduction of Sticky Impurities from the Stomach.
Attachment of Sticky Impurities to the Inner Wall Surface through Contraction Movements
【Step3】
Introduction of Toxic Gas from the Pump Organ.
【Step4】
During the Compression of the Bullet Processor, the Inner Wall Secretes a Special Compound, Detaching Sticky Impurities from the Wall Surface and Encapsulating the Toxic Gas to Form a Bullet.
【Step5】
The Completed Bullet is Transported to the Outside through the Bullet Delivery Duct.
Reproduction & Growth
PUPU, a nomadic creature, encounters limited opportunities for male and female interactions, prompting it to adopt external fertilization for reproduction. During the breeding season, a female PUPU lays unfertilized eggs in a secluded spot, leaving a scent mark discernible only by males. Sensing this unique scent, a male PUPU tracks it down, fertilizes the eggs, and then departs, allowing the fertilized eggs to hatch independently.
PUPU eggs are coated with a sticky substance, and after laying, the female PUPU covers the surface with stones and dust, making it appear like a regular rock. Unfertilized eggs can survive approximately 10 days in the natural environment. When a male finds the egg, it uses acid to corrode part of the surface, exposing the core. After fertilization, the egg returns to its original appearance. PUPUs can lay 5-7 eggs in a single batch, and their high hatching rate is facilitated by exceptional camouflage skills and concealed nesting locations.
【Egg Self-Protection】
【Growth Process】
Fertilized PUPU eggs hatch into offspring in approximately 1.5 months. Newly born PUPUs are fragile and instinctively seek shelter in dark places, consuming soil and gravel for minerals. Fortunately, their growth is rapid, and after around 15 days of hiding, various functions of PUPU mature. Subsequently, they can freely roam the lands of this planet like their counterparts.
Conclusion
To some extent, PUPU and I are really alike. We lead a nomadic life, never picky eaters, and never complain. We are well aware of our identity. Of course, PUPU is more like a janitor, at least beneficial to its world, which differs greatly from me. On a related note, I've always believed that janitors are an indispensable part of the natural order, and human society also has roles like janitors. Take my poor old buddy, for instance; he lost his job to a robot. Can you believe it? At least PUPU doesn't worry about losing its job. I'm starting to envy these lucky little fellows. Hey!
