When they go into the haunted forest, the first shot is a close-up of a sign (I think) that reads: "Haunted Forest, Witches House Ahead (I would turn back if I were you)". Shouldn't it be "Haunted Forest, Witch's House Ahead"? Because the witch owns the house. If it is "witches" then there is more than one witch. Correct me if I'm wrong. But I think they could have fixed a simple error like that!!
