Don't Starve Together: Edition

Having met a Castro crater on your way, destroy it with a pickaxe and go down into the caves to get your achievement. Alarm: the caves are dark, it is advisable to have at least a miner’s helmet for travel, a fireplace, a refrigerator, a cauldron, a tent, a garden bed and a chest that are best prepared but not set up. Bats will fly out of the opened hole at night and attack everyone they see. You can find ready-made camps with tents; unlike similar structures on the surface, these are not traps.
