Sprocket rockets off the springboard, arms flung wide, boots trailing two thin ribbons of morning light. The swings zip past, the oak trees blur into green smears, and the whole park tumbles beneath him in a whirl of petals and laughter. He thought: 'Today, I'm flying.'
Down he goes, tumbling through a fat cloud of yellow pollen that sticks to every bolt and panel like cold honey. 'YIPPEE!' he bounces free, boots thumping the dirt flat in two perfect rings. The whole park holds its breath for one second. Then the wind grabs the pollen and swirls it into a golden spiral that swallows the sun.
ZZZAP. The park peels away like wet paper, and the swings, the trees, the very air turn to static. Sprocket's boots find solid ground, but the ground is smooth black glass, and the walls, the ceiling, the sky above his head are the same unbroken dark. Only sound left: the tiny tick-tick-tick of his cooling gears, no bigger than a watch on the kitchen counter.
Sprocket presses both palms flat against the wall and slides them, slow, searching. A handle. A seam. A door of any shape. Nothing. Just smooth, cold, unending dark that drinks the light off his metal fingers. He thought: 'There has to be a way out. There always is.'
'HELLO?' he calls, and the word bounces back flat, dead, swallowed whole by the black before it even touches him. No echo. No answer. Just the dark swallowing the sound. His metal boots clack in a small tight circle on the glass floor, clack-clack-clack, and that echo is the only other voice in the room.
Sprocket clicks on his headlamp. The pale cone chops through the dark and catches fat specks of dust hanging still, tiny moons drifting in nothing. Far ahead, where the wall meets the floor, a thread of gold light seeps under a gap no wider than his kneecaps. He crouches, and the beam wobbles across his own shiny chest plate.
Sprocket tucks his antenna tight, folds his arms, and wedges himself into the crack. The black presses both sides like thick honey, and he pushes, pushes, pushes. His elbow catches the edge with a shower of bright orange sparks that rain down on his chest plate. He thought: 'One more push. One more.'
His boots clear the threshold, and the light SLAMS in — warm gold flooding every angle, the sharp green smell of freshly cut grass, the distant ring-ring of a bicycle bell on a summer evening. The black peels off him like burnt paper. The park is back. The sun is back. Everything is exactly where he left it, just waiting, patient as a held breath.
Sprocket sits down in the grass, the same green, the same sun, pollen still clinging to his knees in tiny yellow stars. He pokes his dented antenna with one careful finger. It wobbles. He pokes it again. It wobbles slower. He thought: 'Good. Still works. Barely.'
He stands, shakes the pollen off in one big golden cloud, and watches it scatter across the swings and the sandbox. Then he walks. His boots find a new rhythm, steadier than before, each step a clean clack. Clack, clack, clack. The bicycle bell rings again, farther off, and he walks toward it, headlamp still on, just in case.
