Inside the stove, he found a passageway, leading to a set of stairs. This caused him a great deal of worry as well as elation and gladness of living. He did not, however, venture into the oven, but sent his little brother in in his stead. This seemed at first a good idea, but when the brother had been gone three days, he began to second-guess the wisdom of his rash choice. He'd go in after him, he decided. But the passage had shrunk by then, and no normal-sized person could fit through. Yes, that's it, I sent him in because, from a purely physical standpoint, I myself could never have gone. And besides, he mumbled to himself, it's probably nice in there.
