Some may take this as proof that Exotic wasn't lying about its origins, and that Combrobway is a real place, at least in The Bird Feeder universe. I'm not sure, though. Could Lewis be making it up? Could Exotic and Lewis be colluding together to make the others believe that Combrobway is a real place? Or is it all true? Who knows?
If it is a real place, though, I'd love to visit. I'd just make sure to bring my earplugs and/or noise canceling headphones.
