Never heard of a Buffarillo? Why, it's a creature that's half-gorilla, half-buffalo, and all hero. In The Lost Aztiki Tribe and the Mysterious Cave of Gold, Bob and his merry band of adventurers learn of an ancient lost tribe, a missing princess, and a legendary cave filled with unimaginable treasures. That's more than enough to start them off on a journey across the Western plains, but what they will find is not at all what they expect.
