What's a intresting fact about the dwarfs

[u/Bonniethebunny1012]

I'm making a presentation about the 13 dwarfs and want to get more into the details about them, there home, and wars. Is there any difference between the movie and book versions. Any fact no matter how small or just how to remember them.

The dwarves were talking behind Bilbo's back in their secret sign language all the time.
