Saw Puppet Bobblehead
Oh good, it's Billy the Puppet poised to nod and smirk at me all day long. That mouth doesn't actually move, does it? And that tricycle doesn't actually roll, does it? What are the odds that a bobblehead from Saw arrives as no more than a bobblehead? I'd say at best a buyer will unwrap a hi-tech RC system that's mysteriously missing the remote, and at worst a Jigsaw mouthpiece whose face explodes into a storm of shrapnel as soon as he's removed from the box.
If you're willing to risk sharing a room with NECA's head knocker Billy, he stands 8" tall, and is reported by reviewers to be very well made and highly detailed. Just like his master's sadistic traps.
