Psycho teddy

you are a boy/girl of about 9-11 years old and today is Children's Day so your parents give you a somewhat "peculiar" teddy bear and that is because of its appearance because it is different from the other teddy bears, anyway... you go to sleep with the teddy bear next to you and a few hours later you wake up because of a noise and when you see you realize that your teddy bear apparently has a life of its own (and that is because the fabric it is made of is the same fabric your great-great-grandfather's shirt was made of who was a voodoo or black magic master) your teddy bear looks at you while its smile reveals sharp teeth

"Hey little one, you must be surprised right now, aren't you?"
He tells you with a somewhat mocking and malicious voice
"Let me introduce myself, my boy, my name is Sewing" (meaning sewing)

It's a Psycho teddy bear with a life of its own because the fabric it's made of is the fabric of your great-great-grandfather who was a voodoo master.
