This is a lost underground and barely explored cave. The zombies consider it their lair. Skexator seems to be planning stuff out in this cave, and lured many people in. Things are also collapsing from the ground into the cave. The Dump House for example is now stuck in the cave. The way to escape as Skexator stated, the people must solve something with the 3x3 Rubix Cubes and 5x5 Rubix Cube. What also roams around the cave is the Skeleton Dinosaur, who will eat anyone with its sharp teeth.
