Caves are large underground sections of the world filled with unique features. They are so large that they are generated as whole new maps upon entering. Caves have their own artwork, terrain, and maps. Various creatures, plants, and other objects that do not appear elsewhere reside within Caves.
A Cave can be found underneath a Plugged Sinkhole. Upon mining the plug, an open Sinkhole appears with a rope leading down into a new Cave. Each Cave is generated just like a new world. A different loading screen will play while it is created. While within a Cave, time in the world above continues to pass and vice versa.
