Good collection, Daniel.
I meant the “half-small people with large and somewhat V-shaped heads and excessively large eyes” that Billy describes in CR 710:120-121

They may be similar to the “Gray” aliens associated with Roswell who, according to J. Corso *), were not actual extraterrestrials but rather biorobots created by someone to work on other planets
J. Corso: “They had an “oversized incandescent light bulb-shaped head. The eye sockets were oversized and almond shaped and pointed down to its tiny nose… There were no eyebrows or any indications of facial hair. The creature had only a tiny flat slit for a mouth and it was completely closed, resembling more of a crease or indentation between the nose and the bottom of the chinless skull than a fully functioning orifice.
But, so J. Corso, they were “4-foot non-human creatures" who had “bizarre-looking 4-fingered hands” So, J. Corso's Roswell androids were taller than the much smaller and 3 finger-hands-life forms presented in the DW documentary. According to Quetzal (CR215:100) the Roswell androids "resemble their creators", not sure whether this means they exactly match their Reticulum creators or if they are slightly different (i.e., different number of fingers / different height)
For a more detailed description of the Roswell androids and their creators see as well CR 215:74-101.
