The Cave is the fourth world of Donkey Kong Country Returns and Donkey Kong Country Returns 3D. As the name suggests, the levels take place in the caverns. Excluding the secret level, Jagged Jewels, every level in this world either involves the Kongs riding in Mine Carts or Rocket Barrels. In both level types, the main enemies are Mole Miners and Mole Guards, who often change the Kongs' surroundings and attack them often. The world's boss is a mole named Mole Miner Max, who attacks from his Mole Train. This area can be thought of as a tribute to Monkey Mines from Donkey Kong Country.
The cave, as its name suggests, takes place underground, and all its levels appear as such. From the world map, the cave is rather small, featuring five main levels, the boss level, the secret level, and Cranky's Shop. Strangely, it appears to not be underground at all, as if the player uses the "Free Look" option on the map and positions the camera like a bird's-eye view, it has no visible ceiling, likely so it is easier to see. It also appears to be the home world of the Mole Miners, as various houses can be seen in Bombs Away and Mole Patrol. A crystal mine also serves as the setting of Bombs Away, where various collapsing crystals appear.
