Cervantes Tierra is a Terrier, a comic streak with strong opinions about doors. On rainy days Cervantes Tierra drags a pair of goggles claiming to see another layer of reality out and explains it to a different pup each time. Cervantes Tierra is the kind of pup other pups politely refer to twice in the same conversation. Under the jokes, Cervantes Tierra wants to leave The Yard a little brighter than it was found.
