CLASS: BIOCONSTRUCT

   These chitinous Hominid mimics were originally designed to infiltrate remote, untouched colonies of Homo sapiens for covert scientific research, slipping in and out of human domiciles to monitor their most natural, wild behavioral patterns from discrete observation points and harvest tissue samples from unattended juveniles or elders. The Lester's facade is further reinforced by its soothing psionic vibrations and pheromone excretions, while its data is protected by corrosive pseudoblood, amnesiatic gas sacs and a devastating self destruct mechanism initiated by the emergency evacuation of its ambulatory brain.

   Unexpectedly, all research subjects - even including neonates - consistently identified the foreign nature of Lester agents upon close inspection and responded with alarm or even hostility, presumably detecting some imperceptibly trivial flaw in the monster's camouflage and necessitating more careful operation. Fortunately, the creature's imitation of such a weak and appetizing creature remains consistently effective against other monsters.
