Fridge Logic: If they're all trapped in a canyon, just how do they all have enough resources to survive?! Where or how do they get all the food, electricity and water?
They have several orchards, make their own honey, and presumably have several crops.
Who built the locked doors sealing the only exit, and more importantly WHY?!? It makes no sense because the lock is on the inside, meaning someone willfully tried locking themselves in. Also, why would someone with the wood and metal needed choose for the keys to be animal paws? And how did that comboy who drew the map manage to send it back to the starting point of the story when it's already established he died near the exit by getting his arms torn off by cougars? Don't try and think that plotline too hard, lest you get eaten by a Voodoo Shark.
