My children wanted to know what is the Klingon word for the object that the baby Klingon ({ghu}) is shown playing with in the book "Baby's First Klingon Words". If you haven't seen it, it's a baby rattle.
I mentioned their question to Dr. Okrand and here's what he wrote back:
--- begin quote ---
[MO] regarding the baby's rattle: For a baby, an important (defining?) characteristic of a rattle is that it makes noise. On the other hand, this is a Klingon toy, so its resemblance to a weapon is not unimportant. Perhaps it's a {ghu ghanjaq chuS} (though, in everyday speech, this would likely be shortened to {ghanjaq chuS}).

You can see the object in question in this video (at around 33 seconds in):
