5parrow as done by  rabbi-tom at FWA.

What 5parrow is exactly took rather a lot of exhausted, rambling explanation... it's sort of a cyborg, but it makes itself from junk and broken weapons and garbage that it picks up, so it can be comprised of anything. Its face is mostly a gas mask, and it particularly likes to collect eyes.

Jim said he'd already gone one night without sleep, but this thing might just give him nightmares.
