So I've made a race of aliens. They're psychic amphibians that control large warrior mechs by psychically pumping a mucus that they can secrete in crazy amounts (like if a hagfish was the size of a human, imagine how much slime it could produce) to work as a kind of hydraulic control system. And the mechs are fuckin fat bc they have a whole lot of slime deposits that also work as armor against ballistics. Anyway you can see that shit on my bsky. I haven't figured out what the cockpit looks like, but I imagine it's very wet and slimy.
