Rabbit and The Spine were focused.
The Manor was quiet, late as it was. The two automatons sat, side by side and controllers in hand. The expression of pure determination, scrawled across their face plates.
The game was Mario Karts 2.
For too long, as Rabbit had decided, The Spine had held the high score. It must change. Though the copper-bot was finding the game harder than expected.
"I've driven the bus before!" Rabbit nearly yelled in frustration.
"It's always a bit different-"
"Again!"
They started again. They had first begun after the humans ate dinner, which was roughly 7:30 or so. And now it was nearly 2:00 a.m. What was a bit...well, it was one of the easier tracks they had been playing on.
The Spine was seriously considering letting Rabbit win, when there was the heavy footsteps of their brother heard coming towards the room. As he usually did. As he had these past few months.
"Rabbit-"
"I hear him. I secured the kitchen with Steve before he went home." She said.
"And the equipment?"
"Y-y-y-yes, The Spine."
Sleep-hatching, as Peter VI called it. Just as humans (as the robots had noticed a number of times among the Walters) may walk about while sleeping, Hatchworth had developed a tendency to walk, and place things in his hatch while he was supposedly powered down.
The Walter Workers couldn't find why this was. He was running well, there seemed to be no viruses in his system; his virus protection had been updated, and his processor looked at. By all accounts Hatchworth was running smoothly.
At first Rabbit and The Spine didn't notice. Being robots they didn't get "tired" (though it was good for their systems to charge and cool down) and they would usually still be roaming the manor long after all the humans had retired for the night.
They heard him and assumed Hatchworth was just wandering and reacquainting himself with the manor, until the morning when it was discovered that one of Marshmellow's bells was missing. Along with the blender, microwave, some of the Walter Girls hair rubber-bands, and a toolbox.
Still, everyone assumed they had misplaced these things and that was that. Five nights in a row this happened, and then Qwerty revealed some footage of this phenomenon.
This was all six months ago, and since then, with the cause still under-study, they had all learned to take a few precautions. Equipping some of the things in the kitchen with bolts (though it rarely helped) and learning that keeping spares of certain things around never hurt. They also learned Rabbit had an absurd number of melodicas, and a number had been lost to Hatchworth's Hatch.
At that moment Hatchworth entered the gaming room.
"It's still creepy to look at him...ya k-k-know?" Rabbit said, seeing the robot wander from the corner of her eye.
"Yeah."
Hatchworth's body had all the appearances of being shut down. Eyes dimmed. His metal cold, no steam emitting from him. But...he was walking around. It was indeed creepy.
"What happens to humans if you wake them up while they're sleep-walking?" Rabbit asked, putting the game on pause.
"They attack you."
