You’ve stumbled upon a dilapidated Shanty in The Yell Manor Swamp occupied by The Witch Doctor.  He’s held there by Voodoo Dolls cursed by The Swamp Witch and is unable to leave.  Little did you realize by entering you too are trapped by the same curse.  
 
You have 20 minutes to locate the Voodoo Dolls he’s hidden around the room and incapacitate him so he no longer blocks the secret exit that enables you to leave.  Otherwise, end up in his stew pot as a delicious morsel...as has been the fate of many in the past.
