The lipomass (warning: dark)

When a meteorite hits Earth at some point in the near future, nobody could have expected or predicted the horrors that would lay within it. For that meteorite is a vessel for a terrifying extraterrestrial organism -- the Lipomass.

The Lipomass takes the original form of small, almost invisible spores, which rapidly grow wherever they settle into a thick, meaty mass. The mass moves at an astonishing pace, capable of engulfing an entire house within two minutes. Any human who comes in contact with it finds themselves trapped, as surely as if they were flies caught in flypaper. And that's when the really frightening effects kick in.

The Lipomass agitates the production of fat cells in the body, causing them to multiply exponentially. If a 160-pound man is caught in the Lipomass, by the second day, he will weigh 400 pounds. By the third day, 700. By the fourth day, 900. By the fifth, 1200. By the sixth, 1600. And by the seventh day, he will no longer be human. The Lipomass will have removed his head, limbs and other body parts, leaving him as a huge, immobile, vegetative glob of lard. The only way to save a victim is to find a way to pull them free before they reach the blob stage. But speed is of the essence -- if left unchecked, the Lipomass could overrun Manhattan in less than a fortnight. And it's almost indestructible -- nothing short of napalm can kill it. If the Lipomass ever does arrive, it will most likely spell the end for humanity...
