The Windmill World is an area that can only be accessed by getting eaten by Big Red in the Sewers.
Description
The Windmill World is quite small. There are two NPCs inside, interracting with the one near the windmills will send you to The Docks B, interracting with the other will make it spin around. There is a building complex within the map. The door in one of the buildings will lead to the Block World.
