Swee looked at the skitterers that he'd created, rather dissatisfied with the way they'd turned out. Still, there was always a little room for improvement....
Redesign: Recombine all components and create the following pair of forms.
Before beginning: Excise the hippocampus and store it within Swee.
Form 1: The Scout. Base of the scout is a single arm. Migrate all fingers and toes onto this appendage, as well as the associated musculature. Arranger fingers and toes on the bottom of the creature to function as legs. Use a significant (~75%) portion of the host's occipital and temporal lobes as well as one eyeball, one ear, and the bulk of the olfactory system to give the thing a decent set of senses. Make room within what would have originally been the upper arm to house the voicebox and a single lung. Provide enough brain function for the limb to understand simple commands. (Naturally, without a hippocampus, it can't retain these commands without constant auto-repetition, but it should be enough.)
Form 2: the Porter. Rearrange all remaining limbs to be at equidistant points along the torso. Splice spinal column so that the head is now underslung from the porter's tripedal structure. Sever the stomach's connection to the esophagus, moving the stomach so that it's covered by a thick flap of skin and requires manual feeding. Split open stomach cavity, stretch skin and muscle walls to the furthest extent possible, reinforcing with some of the plastic in order to create an openable and exceptionally capacious cavity. Reconnect esophagus to this cavity. On the head, break the jawbone in multiple places, then band it back together in an extended configuration using plastic chunks. Jaws should be able to swallow objects of considerable size to be eaten and passed into the holding cavity via peristalsis. use spliced out bits of spine to lengthen neck so that the head can eat things off the ground. Dole out enough brain to reactivate the most primitive segments related to the consumption of food and the ability to receive simple commands. Do not include much in the way of pain reception, particularly not for the esophagus.
Tl;dr: Create High-Octane Nightmare Fuel creatures.
After: Search for any other nearby addicts. Failing to find any, head to the salvage ring.
((I'm now feeling slightly bad for that addict.))
