Night of the Living Dummy 2: Classic Goosebumps (Book 31)

He's still walking. He's still stalking. Amy's ventriloquist dummy, Dennis, keeps losing his head- for real. So Amy begs her family for a new dummy. That's when her dad finds Slappy in a local pawnshop. Slappy's kind of ugly, but at least his head stays on! And besides, Amy's having fun practicing her new routine. It's like this dummy knows what she's thinking. Like he can move on his own. And it's great- until Slappy starts a routine of his own. A nasty, horrible routine. And Amy can't control him.
