Night of the Living Dummy by R.L. Stine

This is my third Goosebumps book, and I have to say I am a fan of the series, enjoying this one those most so far. Did you ever have nightmares as a kid? Sure, maybe we all did. R.L. Stine knew, and he made those nightmares come true with Night of the Living Dummy. It kind of makes me want to name my next (fictional) son Mr. Wood.

Of the twin sisters, one is a great ventriloquist, and the other sister wants a dummy of her own. They are the type of twins who compete over everything, opening the way for their dummies to cause all kinds of dangerous trouble.
