I created a new world and spawned next to a huge stone mesa. "That's where I'm going to build my house!" thought I and started punching trees. Almost immediately I fell into a cave. I've stripped it of every useful resource and even shovelled the beach to get some sand for my glass windows. With the furnace a-smelting, I decided to dig down from the lowest point of the cave to hopefully get some diamonds for a pick to mine out my obsidian with. Around two dozen blocks down, I found the ****ing Mammoth Cave. I've spent two hours in it, and I'm completely lost. My temporary trunk is filled with so many buckets of waterfall I'll need to carve a staircase back up to get it all out, I have iron, gold, coal, redstone aplenty, I just want to explore every corner of this cave and find the place where I dug down into it to get out.
