Attack of the Jack
R.L. Stine
Devin and his sister Violet are visiting their Uncle Jack for the
summer. When they open a jack-in-the-box, up pops a very ugly, mean-looking
puppet, an old pirate with a dirty red bandana over his
long greasy hair, scars on his cheeks, and a beard, and one eye
missing. Just how much is a pirate’s promise worth?

I really liked it and I didn’t know who Jack was until now

Not my favourite Goosebumps book - no ghosts or mosnters! But if you like pirates, you'll enjoy this.
