I've never seen one before, so I made one. Cuts time in half of mapping caves!
I have to go to school now, or else I would've made more than just earth cave.
One slight problem though...I can't explain it, but you can't have just one cave tile itself, or it looks weird, try it see what's wrong.I made this a whiile ago to day
Shit, the only problem with the mountain is you have to go over the edges with the real thing on the third layer
