A Monster Generator

One of the following monster descriptions is computer generated. Which one do you think it is?

1. It is difficult to understand the shifting lurches and rattling of wagons loaded with bodies.

2. Scraping its barbed forelimbs across its head’s filth-encrusted hairs, this gigantic fly stares mindlessly with terrible multifaceted eyes. It moves in jerks and twitches, wings buzzing unnervingly as it dances in anticipation of impending corpses to feed upon.
