- The revelation that eternally pessimistic Puddleglum is considered to be giddily cheerful by his fellow Marshwiggles.
Puddleglum: If they've said it once, they've said it a thousand times. "Puddleglum," they've said, "you're altogether too full of bobance and bounce and high spirits. You've got to learn that life isn't all fricasseed frogs and eel pie. You want something to sober you down a bit."
