What metaphors are used in James and the Giant Peach by Roald Dahl?

Example of Metaphor:

Aunt Sponge was enormously fat and very short. She had small piggy eyes, a sunken mouth and one of those white flabby faces that looked exactly as though it had been boiled. She was like a great white soggy overboiled cabbage. Aunt Spiker, on the other hand, was lean and tall and bony, and she wore steel-rimmed spectacles that fixed on to the end of her nose with a clip. She had a screeching voice and long wet narrow lips, and whenever she got angry or excited, little flecks of spit would come shooting out of her mouth as she talked.
