The Stone Maze is an area that is accessible from Chocolate World by interacting with the pink, blinking, cone-headed portal.
Features
The maze is made of gray stone or concrete with a scrolling background of a blood splatter. There are a lot of Scary Faces in this area that will send you to an isolated area if you are caught.
To get to the Bowling Zone, travel eastward until you see a dead-end. At that dead-end, head north, then turn to the east at the first intersection. Go south at the next intersection and continue until you see a red bowling ball (this is the portal).
Kanashii-Tan can be found by going in the following directions at the first-encountered intersections (starting from the intersection right before the portal to the Bowling Zone): east, south, east. There should be a small, tunneled entrance; Kanashii-Tan is inside this room.
If you take a left at the intersection right before the Bowling Zone portal, then go north at the second intersection after that and continue north, you'll encounter a portal to the Spelling Room.
