If you've got a geek (or Jedi) in training, you're probably going to want them to be multilingual . . . and I don't mean languages of this Earth. The How to Speak Wookiee ($17) book is perfect for your little ones who are preparing for a lifetime of inter-galactic space travel (pretend, or otherwise).
As you probably know, Wookiees are notoriously short-tempered, so prepare your children (or heck, even yourself) to converse appropriately and politely in the language with this handy book and audio module that helps them to speak like a native. Pretty adorable, pretty geeky.
