A cave located in the Snowy Hills.
Entrance to Rock Crab Cave
The cave is filled with lots of monsters: Crystal Spider, Rock Crab, Crystal Warrior and the mighty Karactor, Lord of the Moist.
Inside the cave, you will also find several bonfires (useful for cooking mushrooms, which can also be found) and a Rock Chest, which will give items or coins if you have a Rock Chest Key, which Karactor drops nearly every time he is killed.
