Jane the Puppet

You were holding the box your grandfather had given you, and sitting on the edge of the bed. You hear a crash followed by the panicked voice of your little sister, Yumi. You swung the door open to see a monstrous teddy bear, resembling the one that one of your new mothers had given her. You then remembered the words of your grandfather. You yank Yumi into your room and lock the door. You set the box on your bed and open it… A dummy? How will this help us?! You move your fingers under the back of the dummy's shirt, only to have it come to life in your hands, and yell at you for touching her. There was a crash, and Yumi whispered: “T-teddy bear…” There is a puff of smoke, and there is a (quite lovely) woman where the puppet once was. She pulls out a knife and walks towards the door, with a grin, and opens it. As soon as the “teddy scare” sees the puppet, it stops dead in its tracks. Within minutes, the bear is a pile of ripped stuffing and cloth.
