I found a signal that was labeled as "possible cave opening", but the problem was it was below 1,000 meters. Sorry, but I used a oxygen cheat to dig to the signal. while 200 meters away from the signal, the hole opened up into... eh... something. Had a sort of flat ceiling but had some big bulges along with some stalactites. The water color is like at a 50 meter color. What would this biome be called?
