The enormous machine jerked to a stop, and hissed. The red light turned off, and a corresponding green light blinked slowly through the gloom.
The old man shuffled forwards, a heavy bucket swinging from his arm. He approached the enormous bulk of the machine, whose powerful rams loomed over his head menacingly. Hydraulics creaked and groaned as the systems cooled, but the old man didn't register them. He had creaks and groans of his own.
He placed the bucket beside the flank of the machine, and used one of his many jangling keys to open a small door in the metal. It cracked open, spilling an icy smoke to the floor before creaking fully open.
"Good job Squiddy, good job," the old man crooned, offering his cupped hands to the opening. He bent at the knees, eliciting more groans from his old frame. "Come on now, we're done".

A black tendril jerked out of the doorway and slapped itself against the machine. Thick as a man's finger but boneless, it arched powerfully forward. Two more tendrils shot out and suckered themselves around the door. The green blinking light glistened on the dark wet skin, and as the smoke finally dissipated, a fat shiny body hauled itself to the edge of the doorway, hauled by its muscular tentacles.

The old man crouched further, offering his hands almost in prayer to the black mass now perched on the edge of the machine, quivering. With one slick movement, it detached its grip and fell into his waiting hands, which plunged downwards into the bucket. There was no splash. There was no sound.

"Eh, dear dear, let's get you fed," tutted the old man as he rose on his stiff legs. He picked up the bucket, and shuffled away.

I'd continue, but I don't want you to have nightmares or owt.
