The doll pretends to be harmless, when in reality it is a monster trapped in a doll-like body. It is evil and seeks revenge for humans because they were the ones who trapped it there. Anyone entering the house is now the dolls target, she will make the house do weird things like moving things around, time travelling, changing of seasons (e.g snow inside the house), making mirrors show whatever she wants them to and torturing anyone entering the house until they go insane and kill themselves.
