Attack of the Jack!

Devin and his sister Violet are visiting their Uncle Jack for the summerI at his old house by the seashore. Jack was a sailor and collected strange and fascinating items from the sea. Devin and Violet discover a locked trunk that they manage to get open. It's filled with antique jack-in-the-boxes and one box is hidden under the others, covered in dust. 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. "Thanks for letting Sailor Jack out!" he rasps, bouncing on his spring.
