A local legend in Greely Valley, Iowa: insert a golden token into the jester's mouth on the tombstone of Ludwig von Tökkentäkker, and a haunted amusement park will rise from the cemetery ground. During a Halloween hayride, one visitor locates the token and inserts it. The legend was accurate. The carnival rises. The exits close. The only weapon available is a shotgun pulled from the shooting gallery. The way out runs through the Haunted House, Rickety Town, and the Freak Show before reaching the Big Top, where Tökkentäkker waits aboard his airship. After surviving and destroying the airship, the protagonist wakes outside the tombstone in the morning — and then inserts the token again.
