First things that came to mind were of course trees, flowers and plants. Why, because they're all around us. Next I tried conceptual sketches of my monsters, 'Wurms', along the lines of a scientific journal. This all makes sense when combined with Tesla's lost journal and the one invention he didn't share with the world. What, you've never heard of it?
I discovered that all monsters are not equal, feedback one one sketch, "Is it eatinga 'Fig Newton'?"
Careful examination revealed that it appeared so, after the fact.
