I really liked what C. Hodgson and D. Thiger have done with some weird alien n monster substances, so I wanted to give something similar a try.
With a couple of these I tried to mimic some of their effects while adding my own twist. The rest are mostly just experiments in how strange, slimy or creepy I could make it.
