Conceit, since you're so enthusiastic about it, i'll see what i can do. Are you suggesting that your part of the snake would be the very same snake i have in my tile and it's somehow circulating inside the mountain? Your story about the alien invasion makes a lot of sense too.
Exactly! yeah you got it. it's circulating inside the mountain because inside the mountain is filled with that black liquid (which I call dark matter), so in a sense the Snake swims inside the mountain. so inside the mountain the native chemical which is lava, is fighting off the invading chemicals which are the green ooze and the dark-matter =O.
Coran!....what are those...meteorites? hahahahah I never saw that coming, good for you! Dont worry about the greys tho, listen to Ptoing...while there isnt a strictly grey highlight, you can use a green or blue highlight to replace it...making it work is the challenge!. You CAN make a rock-like textures with it...if you need some examples check to the left of our mountain, around the big alien that's extending it's tendrils downwards...there are some very nice rocks to the left of him.
EDIT: w000t! metal fox is in it too! the green ooze shall invade you all XD
