Sandcave

The Sandcave is a biome that can be found in two locations: beneath the Pyramid, and in between the upper Overgrown Cavern and Power Plant.

About
The biome consists mostly of sand, rusty ground, and sandstone arranged in solid structures, somewhat similar to the terrain formations in the Underground Jungle. Numerous unexploded naval mines litter the area, especially in the many pools of water found here. Aside from a single exception, there are no pickups or Treasure chests here, only enemies.

The entire biome is about the size of the Coal Pits, but deeper and slightly narrower.
