What childhood toy of yours would make a GREAT horror story?

We were all children at one point. Children destined to grow into disturbing masters of horror, but children nonetheless. And anyone who has kids/has babysat/has little siblings/has ever seen a horror movie KNOWS that kids have some creepy toys.

So - what creepy toys did you own that would make a great horror story?

As for me, we couldn't afford a Furby when I was a kid, so I had a creepy off-brand thing called a Wuv Luv. I loved that thing, but looking back on it now… Jesus.

Also, basically every doll I ever owned was pretty disturbing.
