Human: Produce a detailed written description of a spooky scene outside a town square with a mural and a fence. Assistant: 
The cobblestones turn through an area of tightly clustered cottages set across from a high wooden fence that borders the street, forming a narrow alleyway. Some local artist has painted the fence with a fanciful mural of a group of trolls and giants engaged in some bloody sport. Clumps of grass and a few weeds grow along the fence and between the old cobblestones.
