Water Monkey

Region/Culture: China
Mythos: Chinese Mythology
Primary Type/Nature: Monsters and Beasts
Mythical Attributes: Drags swimmers, animals, and bank-walkers into the water with strength wildly out of proportion to its size, drowning them and sometimes drinking their blood.
Role in Mythos: Aquatic yaoguai of canals, lakes, and slow rivers, often identified with the shui gui or water ghost, the restless soul of a drowned person seeking another body to take its place.
Relation to Humans: The water monkey preys on people who venture into or beside its territory, gripping legs from beneath the silt and pulling them under. In the shui gui tradition the creature is the spirit of someone already drowned and bound to its place of death, requiring a substitute drowning, the so-called tì shēn or “body replacement,” before it can return to life.

A canal in Jiaxing turns the color of weak tea after rain, and the rice merchants who haul their carts along its bank know to keep one eye on the water. The story they tell is short. A man and his ox were walking the path beside the Yellow Mud Canal when a black hand came up out of the silt and took hold of the ox’s leg. The ox went down. The man went after. Neither came back up. People who lived nearby had a name ready for what had done it, the way villagers always have names ready: shui hou zi. Water monkey.

The creature is one of the most insistent presences in Chinese folk belief, though it almost never appears in the formal pantheons. It belongs to the canals and the lake edges, to the ponds no one swims in twice, to the slow stretches of river where the surface goes glassy and the bottom is thick mud. Where someone has drowned, a water monkey is assumed to live, and where a water monkey lives, someone will drown. The logic moves in both directions and resists tidying.

There are essentially two versions of it, and they bleed into each other. In one, the shui hou zi is a small amphibious primate, hair plastered flat with river water, capable of clinging to a swimmer’s leg and pulling them down with a grip that has no business being that strong. It comes onto the bank between rains, picks scraps of fish out of the reeds, and climbs into the low willows that lean over the water, where it waits and watches. Its presence can sometimes be detected by smell. The fur stinks when it dries. Older accounts give it a turtle-like shell across the back, and this older form is widely thought to be the Chinese ancestor of the Japanese kappa.

In the other version, the water monkey is not really a creature at all but a ghost. The shui gui, the water ghost, is the soul of someone who drowned and never received the rites that would let them move on. They wait at the place of their death. They are hungry. Their freedom requires what folklorists call tì shēn, a body for a body, the substitution of another person’s drowning to release them. The black hand around the ox’s leg in Jiaxing was, in this underlying logic, the hand of someone who had once been pulled under themselves and now needed someone else to take their place. When the ox and the merchant went under, the ghost rose somewhere else in the canal, alive again in a borrowed shape, and the merchant took its turn at the bottom, waiting for the next walker on the bank. The cycle does not end. It only changes who is doing the waiting.

Yuan Mei collected several of these stories in the eighteenth century in his Zibuyu, “what the Master would not discuss.” In Kuaiji, a tailor was nearly pulled into a river by a cluster of small, naked, black-faced things that swarmed out of the water at dusk and clung to him with cold hands. J. J. M. de Groot, the Dutch sinologist who spent decades cataloging Chinese religious practice, noted that whenever a corpse was hauled from the silt with its arms or legs sunk deep into the mud, every villager in the area was sure of the same thing. Something had been holding on.

The water monkey has an ancestor in the older texts, though they may or may not be the same being. In the early ninth century, a fisherman in Chuzhou on the Huai River was said to have hauled up a creature with a black body and a white head that fought like a thrown net of muscle, and this was Wuzhiqi, the monkey-shaped flood demon who had to be subdued by Yu the Great when Yu was setting the rivers in order during the Great Flood. Yu chained Wuzhiqi beneath Turtle Mountain. The chain held, more or less. Some versions say its end can still be seen at the foot of the mountain when the water of the Huai runs low. The water monster is bound, but only barely, and the binding is provisional. Anything kept that close to the surface is going to come up eventually.

Powers in this tradition are simple and brutal. The water monkey can grip a person or a horse or an ox with a strength that defies its size. It moves under the surface without disturbing it. It has the patience of something that does not need to breathe air, which is to say it has no schedule and is in no hurry. Some accounts give it a taste for blood, drunk from the drowned. The shui gui version brings the additional weapons of intelligence and grievance, the calculation of a being that needs a particular kind of death to occur and is willing to wait years for it.

The weaknesses are the weaknesses of any tethered spirit. The water monkey cannot leave its water, or cannot leave it for long, or cannot leave the precise stretch of canal that has become its territory. The shui gui is bound even more tightly to the spot where it died. Proper funeral rites for a drowning victim are said to break the cycle, releasing the soul so it does not have to claim another, which is why villagers in some regions go to considerable trouble to recover a body, even at risk to themselves. The alternative is leaving an unsatisfied thing in the canal.

There is a long shadow behind the water monkey, and it is the shadow of how often, historically, people in rural China drowned. Children especially. The creature did the work that warning signs do now. The folklore was moral instruction in the form of a thing with hands.

What powers does the Water Monkey have?

The Water Monkey can command water, summoning it to rise or fall at will. It can create pathways across rivers and conjure small storms. These abilities reflect its dual nature as both a nurturing guardian and an unpredictable trickster, mirroring the qualities of water itself.

What are the Water Monkey’s weaknesses?

The Water Monkey cannot stray far from the river or lake it guards, since its power is tethered to that specific water body.

This combination of physical limit and personality flaw gives clever travelers a real chance against the Water Monkey.
