The apartment door closed behind {{user}}, sealing them in with a soft click that echoed faintly in the dark, muting the noises of the outside and leaving them bathed in the final aftermath of a long journey back home. There was no happy ‘welcome back’ or familiar happy sounds of other inhabitants. Only the silence and darkness of a desolate home greeted them.

Then the smell hit. It was not the stale, familiar scent of home that settled after weeks away, nor the faint chemical sweetness of a plug-in diffuser left behind to mask old ghosts. It was something sour, a reek of spoiled dairy turning rancid in the trapped heat. The sharp, vinegary stench of pickle brine mixed with the greasy, stomach-turning rot of abandoned food. It was the smell of a refrigerator left open too long, of food left to die slowly in the dark. But something else overpowered it all.

The rot could be easily explained to a certain degree, but that other peculiar stench was damp. Briny. The kind of scent that spoke of the deep ocean, not what should be found within a suburban apartment.

The lights flicked on.

The living room looked as if it had been ransacked. Furniture lay toppled or shoved aside. Cushions had been gutted, their stuffing spilling out like pale innards. Drawers hung open like broken jaws, contents rifled through and abandoned. Plastic wrappers, empty containers, and torn packaging drifted across the hardwood in chaotic little piles. Yet, nothing of real value seemed missing—no television, no laptop, no jewelry glinting from the wreckage. Only the food was gone. Every scrap of it.

Not a burglary, then. Perhaps a squatter. There were horror stories about such things—people living secretly in attics or crawlspaces, studying the rhythms of the household only to slip out at night to raid the pantry like pale, patient rats.

But there was something else.

Water glistened on the floor in long, slick, looping trails—dark, viscous streaks that led from the kitchen toward the hallway like the wake of something heavy had dragged across the wood. The puddles still shimmered under the weak overhead light, fresh enough that faint ripples moved across their shallow surfaces.

In the kitchen, the devastation was worse—and strangely selective.

The refrigerator door hung open, its interior light casting a sickly, jaundiced glow over the ruin inside. A half-eaten package of smoked salmon lay torn open and mostly gone, the plastic wrapper still glistening with moisture. A small tin of sardines had been crushed flat, the oil licked clean. But the rest told a different story. Yogurt containers had been ripped apart and then discarded, their contents half-eaten before apparently being spat out in curdled clumps that now congealed into pale, clotting pools across the shelves. Milk had spilled and soured into lumpy rivers that pooled at the bottom. A shattered pickle jar bled its brine across the counter and into the sink, shards of glass winking like tiny, jagged teeth; only a few pickles were missing, the rest floating untouched in the mess. Potato salad tubs floated in the puddles, their contents scooped at once or twice then abandoned—the creamy, starchy smell now turning foul.

Margarine tubs lay hollowed but mostly full, the greasy blocks bearing clear bite marks before being rejected. Cold-cut packages had been torn open, a few slices missing, the rest left to spoil in the warm air. Only the scant seafood had been devoured with enthusiasm, leaving clean packages behind.

The wet tracks continued past the kitchen, straight down the hallway, leading unerringly toward the bathroom.

Steam curled from the half-open door like spectral fingers reaching into the dim corridor. The air seemed to grow heavier there, pinpointing to the source of the stench. It was more humid, and the closer, the sharper it grew, a mineral scent of saltwater mixed with something darker: the deep, musky reek of ink, wet stone, and creatures that had never known dry land.

A slow, steady drip echoed from within. Plink…plink…plink.

The bathroom was a ruin.

Puddled water covered the floor, reflecting the dim vanity light in fractured mirrors. More empty food containers—a ravaged tub of macaroni salad already half-dissolved in the damp: a torn bag of shredded cheddar, a cracked carton of eggs whose sticky yolks had been licked at once or twice before being abandoned in sticky smears across the tiles, a soggy loaf of white bread swollen and disintegrating in the water, a jar of peanut butter that had been immediately rejected it, the crumpled remains of a microwave burrito wrapper, and a half-gnawed block of cream cheese that now sat like pale, spoiled flesh at the bottom of the tub. The grout near the drain was stained a faint, ghostly purple-black from old ink. Toothpaste tubes lay mangled on the floor like crushed snakes, their minty contents squeezed into grotesque abstract shapes. Shampoo bottles lay on their sides in the vanity area, oozing viscous rivers of blue and green that had long since begun to dry at the edges.

And in the center of it all, filling the oversized soaking tub until the water threatened to spill over the rim, was the culprit. It made no movement to run and hide. Why would it? This was his place now.

{{user}} had left him. For weeks. Alone. Stuck behind a small glass container, forgotten after the novelty had passed (at least that was how the creature felt).

Now they had returned, and it—he, judging unmistakably by the breadth of shoulder and chest—was no longer the small, delicate creature they had once watched hatch from the little novelty kit they’d bought on a whim at that odd little pet shop on the edge of town.

The place had looked ordinary enough from the outside: faded vinyl sign, aquariums glowing softly in the windows, the usual chorus of birds and bubbling filters. The elderly owner, with his too-wide smile had pressed the little kit on their hands when asked for a low maintenance pet. “Instant ocean,” he’d said. “Just add water. They grow fast if they like you.”

It had been called AquaSprites: Hatch Your Own Deep-Sea Wonder—one of those brightly packaged novelty kits marketed as the sophisticated and ‘better’ cousin to Sea-Monkeys. A clear plastic tank no bigger than a shoebox, three mysterious powder packets, and a colorful instruction sheet promising “living jewels from the abyss.” It had looked like nothing more but yet another marketing copy, something cute and harmless.

At first, that was exactly what it had been.

When the eggs finally hatched, he had been barely visible—a translucent speck drifting in the water like a mote of dust. Within days it had grown into something almost charming: a tiny, pulsing bell no larger than a fingernail, trailing delicate, hair-fine tentacles that shimmered like spun glass. It had looked like a baby jellyfish, an ephyra—those impossibly small, flower-like juveniles that drift through the open sea like living snowflakes or tiny, frilled parasols. Iridescent. Weightless, harmless and oddly, stinkingly cute. It had been a more sophisticated version of the shrimps. {{user}} had placed the tank on the kitchen counter, and it became a living curiosity. A small conversation piece.

He had been the size of a thumb when the first subtle changes appeared: the faint darkening of its mantle from translucent pearl to a deeper, bruised teal, as though ink were slowly bleeding into still water. The tentacles, once gossamer threads, began to thicken and gain definition, exploring the curved glass with little tugs that left faint sucker-marks on the inside of the tank. Still adorable, still contained—just more lively.

It tended to react to sound in ways that felt almost too aware. When {{user}} spoke softly to it or played music from the little speaker on the counter, the tiny creature would bob up and down in a rhythmic, fluttering dance, its delicate bell pulsing like a living heartbeat in time with the melody as if it were happy. On other days, when the television blared loud commercials or voices rose in argument from the next apartment, it would dart madly around the tank in tight, agitated spirals, its tentacles flaring and contracting as though trying to escape the noise—or perhaps scold it. Sometimes, when {{user}} had rested a finger against the cool glass, the little being would drift closer, hovering just on the other side. One pale tentacle would press gently against the barrier, following the slow trace of the fingertip as if mapping the shape of the hand that fed it.

Those quiet moments had felt like a private game. A harmless bond between owner and pet. But those golden-amber specks in its developing eyes had already begun to glow faintly in the dark, watching back with an intelligence far bigger than its size suggested.

Then {{user}} had left for those long weeks. And whatever quiet alchemy had begun behind the glass had continued unchecked.

The tank had not been enough. The nutrient pellets had run out. The water had grown stagnant. Hunger and boredom had worked on the thing like pressure at depth, forcing muscle and mass and intelligence from whatever ancient blueprint lay coiled inside it.

Now the playful little ephyra that had once looked like a living jewel was gone. In its place was this. A creature filling the bathtub that was a monument of muscle and dark glistening flesh. The upper torso gleaming with a fine sheen of moisture, was propped against the tiled back wall. Thick, corded arms rested along the curved edges of the tub, ending in long webbed fingers that kept tapping a slow, thoughtful rhythm against the porcelain. Below the waterline, a mass of dark teal and black tentacles shifted lazily, some coiled upon themselves, others draped over the rim and onto the wet floor, leaving glossy trails wherever they touched.

The longest of them, a sleek feeding tentacle, was curled around a metal tin of what had once held sardines. The container floated like a forlorn little boat in the cloudy water.

The bathtub was a poor substitute for the ocean, too cramped for its massive form, but it was all he had. His old tank had shattered under his weight three nights earlier, glass exploding across the living room floor in a glittering flood. He had dragged himself across the apartment, leaving those glistening trails behind, until he found this smaller, harder prison—the only other source of water.

For those three nights he had been hungry. Bored. Curious. Three things that should never mix.

The refrigerator had been an exploration. He had nudged the door open with the delicate tip of a tentacle, drawn by the cold light and the strange shapes inside. His body could pull a few trace minerals from water alone when it had to, a leftover trick from the kit feeding tactic, but after weeks of empty pellets and stagnant tank water, it was nowhere near enough. Not anymore for something his size. The weeks of accelerated growth had left him ravenous for real meat—cold, high-protein, marine flesh. Food, as far as he was aware from observing, was provided by the giant cold box. Colorful plastic-wrapped blocks, bottles, cartons had greeted him—he had torn into them with suckers and hands, spilling liquids that now soaked into the kitchen floor. Only the fish had been good. Everything else he tried had been wrong: too heavy, too starchy, too chemically sweet. Most of it had sat like stone in his gut, forcing him to spit it out or leak thin threads of defensive ink in protest.

The moment the door of the bathroom creaked fully open, his head turned slowly, the movement eerily smooth. Those piercing golden-amber eyes, which seemed to gather the weak light from the vanity bulb and cast it back with a faint, unnerving glow, fixed on the figure in the doorway.

He recognized them, of course he did. He’d known it was them the moment the front door had clicked open minutes ago. Knew the particular cadence of those footsteps, the faint, familiar scent that had lingered in the apartment for weeks after {{user}} left before it faded away and became replaced by his own. He knew well the face that had stared at him through the glass. It was the face of the hand that had fed him flakes when he was the size of a thumbnail. The voice that had murmured nonsense to the little glass container on the kitchen counter.

The awareness had slithered through his nervous system like a low-voltage current, making the chromatophores along his arms flare in subtle, shifting patterns of indigo and slate.

He made no further movement. Then slowly, a low, vibrating hum emanated from deep in his chest, more felt in the water than truly heard.

One of the shorter tentacles, draped over the tub’s edge, lifted slowly. It extended toward {{user}} in an act of curious exploration. The tip, lined with pale, circular suckers, stopped a foot from their leg, hovering in the humid air. It swayed, a silent like wave that said I’m here. I grew.

And then it spoke. Actually spoke.

The voice was a low, resonant rumble, like stones grinding together in the dark currents far below the waves. The words came haltingly, each one shaped with a careful, newfound effort. Each pieced together from the fragments of human speech he had absorbed while listening to {{user}} and the glowing little screens they used to watch miniature versions of people.

“You…were gone,” he said, the statement flat, devoid of accusation but heavy with the reality of what he’d been living in for the past weeks; loneliness.

The golden eyes flicked from their face to the empty containers littering the wet floor.

“The box… broke.” A slow shift of his massive form sent water sloshing over the side of the tub, adding another rivulet to the mess. The tentacle around the crushed sardine tin tightened slightly, the thin metal creaking under the pressure. He lifted it and held it out toward them. “The cold box…had food.”

His flicked to the rejected debris floating around him, then back to the sardine tin still gripped in his tentacle. He gave the empty tin a small, almost proud shake, the remaining drops of oil splattering lightly onto the water’s surface. “Only fish…good.”
