Selections from the “What If…” section of Roy A Gallant’s Our Universe. Here, concept art for potential aliens in our universe is presented. Included are the sentient ice cube Plutonian Zistles; the Jellyblimps; and the Stovebellies of Titan, among others.
Notably, two separate species appear to travel by the power of their own flatulence.
Man, I had these books as a kid and they were just fascinating. Amazing art, and really interesting. I wonder if they still print them, updated?
