How does haroun hope to make his father happy?

Haroun runs into a man who he thinks looks something like a parrot. The man tells him his name is Butt, “driver of the Number One Super Express Mail Coach to the Valley of K.” Haroun as an idea and asks Butt if he will take him and his father to see the beauty of the road from the Town of G to the Valley of K, a road that climbs “like a serpent through the Pass of H towards the Tunnel of I.” Mr. Butt protests that it is late, but decides that he will fulfill the young man’s request.
