The storm had passed the night before, leaving the park soaked and glistening with dew. Puddles littered the sidewalks, and the grass squished under every step. Toby and his three friends wandered through the muddy playground, the air still heavy with the scent of rain and earth. Laughter echoed across the empty park as the boys stumbled upon a trail of snails slowly crossing the pavement, their slimy bodies glistening in the pale morning light.

"Gross!" Toby sneered, lifting his foot and smashing one beneath his sneaker with a sharp crack. “That one popped!”

The others laughed, and soon they were stomping, kicking, and flicking snails one after another, treating the trail like a game. Little did they know that the air had changed around them—thicker now, humid and strange, almost pulsing with some unseen energy. The laughter died down as Toby suddenly paused, clutching his chest.

“Ugh… guys, I don’t feel so good.”

He hunched over, coughing violently. Thick, glistening mucus dribbled from his mouth, stringy and iridescent like snail slime. The sound of his hacking echoed unnaturally, as if amplified by something deeper than his lungs. His friends backed away, unsure whether to laugh or panic.

Then, Toby’s legs buckled. He dropped to his knees, groaning. His arms trembled, fingers twitching, and his skin took on a strange, clammy sheen. With a wet tearing sound, his shirt burst open from the back as something hard and round pushed through—an embryonic spiral shell, slick and pulsating as it slowly unfurled and hardened into a glossy, swirling carapace.

“What the hell!?” one of the boys gasped, stumbling backward.

Toby whimpered as his arms began to shrink, retracting slowly and painfully into his sides. His bones cracked with sickening snaps, fingers folding inward until only soft stubs remained. His legs stretched and twisted unnaturally, the flesh between them melting together into a thick, muscular foot. His sneakers split apart as his legs fused into one long, slimy appendage, glistening with fresh mucus. His pants sagged off and fell behind him like shed skin.

He screamed, but it came out as a gurgling rasp. His face began to stretch forward, nose flattening as his mouth elongated into a blunt, lipless opening. His eyes bulged outward, tearing through the skin as they extended on long, quivering stalks. The skin around them shimmered, darkening and slickening into that unmistakable snail texture.

Toby, now no more than a human-sized slug with a fresh shell mounted on his back, twitched and writhed, groaning in muffled horror as he slid helplessly in the dirt. His friends screamed and ran—but it was too late.

The air around them shimmered again, as if reality itself was sweating. One by one, they fell to the ground, coughing and choking just as Toby had. The same mucus poured from their mouths, and their limbs began to convulse, fingers melting into smooth nubs, their arms shrinking as their backs arched and split open to reveal tiny shells that quickly grew, spiraling outward like grotesque flowers blooming from their spines.

Each of them transformed, unable to stop the process—legs fusing, skin slickening, faces reshaping until all that was left were four oversized garden snails, wriggling slowly and pitifully across the same paths they once desecrated. Their punishment was clear: to live as the very creatures they mocked and destroyed, cursed to spend their days dragging their slimy bodies along the wet earth, feeling every grain of dirt beneath them.

And so, the park fell quiet once more. The only sound was the soft, wet squelching of four giant snails slowly sliding away, the rain clouds parting to let in the morning sun, glinting off the trails of slime they left behind.
