Experimented with a GameBoy palette and made some critters: Hermit crab, Isopod, TEETHWORM, and a frog.
teeth worm is a great name
I just realised as I was about to fall asleep that I had typed this out all wrong. I edited the titel and description now, but for anyone reading the comments let it be known that I fucked up.
This is just the regular Game Boy palette, innit? These are some good critters, though - my favorite is the ammonite-looking fella in the top left
