Doc & Sprocket
Even though you get to Fraggle Rock through a hole in the wall of his workshop, Doc doesn't know anything about the Fraggles. That doesn't mean he's not smart! He's invented a ton of stuff, like the automatic dog-feeder his dog, Sprocket, uses. Sprocket's a good dog. He's seen Gobo, but he's not saying a word. Or is that just because he can't talk?
