Just caught up through iTunes on the 3rd season.
I would have never guessed that Gungan saliva is waterproof, and also acts as a bonding adhesive. I guess the mystery of how they built Otoh Gunga has been solved.
I wasn't too enamored with that shark-headed henchman of Dooku. I am trying to imagine the conversation with George Lucas and David Filoni:
George: We need a henchman of Dooku that can live underwater.
David: Well what kind of animals live underwater that would be considered evil?
George: How about a shark?
David: Ok, great we'll go with that. How should it look?
George: Put a shark's head on a humanoid body.
David: Ok, great, thanks!
