The Overworld is the main, default area a player spawns on in the game Minecraft. Almost every biome is there except for The Nether and The End. It serves as the "planet" of Minecraft, resembling a cubic imitation of Earth's natural landscapes. Many passive, hostile, or neutral mobs made their homes in here.
The Overworld appears in all of SMG4's Minecraft bloopers, as the main setting. It is constantly grieved by Mario's careless actions.
