The room was small and square, with two open security doors on either side. A simple chair was in the back, with a desk and a fan at the front. Posters embellished the wall advertising the establishment: "Freddy Fazbear's Pizza! Fun for the entire family!" A man walked in with toolboxes, an acoustic guitar and a single, large, wrench. The man set down his equipment and spread some metal parts on the table. What was left of the sun slipped below the horizon, leaving only dark purple streaks of cloud and an uncharacteristically black sky. The man with the wrench, tool boxes, and an acoustic guitar looked at the watch, 11:30, and sighed. His work here had begun.
The whack of a wrench on an unfolding hunk of metal reverberated through the room with a deafening sound in the blackness. The hunk of metal slowly unfolded, turned on its axis and displayed a gun barrel. The sentry gun started its customary rotation, its gaze penetrating into the hallway. The owner of the wrench wiped sweat from his brow and arched them as there was a crash from the opposite opening. Moving with some semblance of urgency now, he lifted a blue toolbox and sent it thudding on the doorway to the open, black hallway. As the mini sentry gun unfolded with a startling speed, something in the black hallway moved. The shape took on animalistic visage, bunny ears sticking straight out, the shuffling stiff gait describing inhuman and metal, though possessed with a kind of spirit. The bunny man clanked on small step closer with the stamp of metal on metal. The mini sentry, now complete with a rotating red strobe light on its back, turned and fired 10 20 caliber armor-piercing rounds into the animatronic, shredding its insides, wires and sparks pouring out. The bunny man's head jerked back once, twice, and clattered to the floor, jerking with a disturbing trait that reminded the engineer of a human in the death throes of execution. The engineer turned his back as the bunny man animatronic emitted an electronic sound that sounded vaguely like a young boy moaning in despair. Moving quickly, the engineer grabbed a fistful of metal from the dispenser in the room and affixed them to his first sentry gun. Twin streams of ammo from Gatling guns poured into the hallway as the engineer settled down into his chair, picked up his guitar and strummed it. Both guns started to fire a stream of bullets as the engineer started to play a tune.
5:30 AM. The early morning sun showed signs of light indigo through the morning. The engineer packed up his guns and went into the hallway and hauled in the shattered animatronics. Holding them up to the dispenser, the healing beam shot out as pieces of metal rode with it. The scanner read the schematics and the damage done, pulled out whatever shrapnel that hadn't gone straight through (which was almost none). The metal parts and wires, clanged back into place. The engineer repeated this for each animatronic and reprogrammed each of them with his self designed tablet, then put them back into the room, fully fixed and whole, shining and bright with the rising sun. 6:00. The engineer took his tools, guitar, and boxes carrying who knows what and strode out the door into the morning. Each night he did this, killed the animatronics when they got hostile and patched them up before morning before they got hostile again. He didn't know why. The engineer whistled a tune to himself and walked away.
