...for the first time Rincewind saw the troll. It wasn't half so bad as he had imagined. Umm, said his imagination after a while. It wasn't that the troll was horrifying. Instead of the rotting, betentacled monstrosity he had been expecting Rincewind found himself looking at a rather squat but not particularly ugly old man who would quite easily have passed for normal on any city street, always provided that other people on the street were used to seeing old men who were apparently composed of water and very little else. It was as if the ocean had decided to create life without going through all that tedious business of evolution, and had simply formed a part of itself into a biped and sent it walking squishily up the beach. (...) How does he hold himself together, his mind screamed at him. Why doesn't he spill?
