What are the character traits of (centipede and spider)?

Centipede is one of James' friends on the peach. James is initially scared of Centipede (and of all the peach's other inhabitants), but soon learns to like this gigantic, wisecracking creature. Centipede has 42 legs, is very particular about his boots, and is in the habit of telling stories through songs (which often are often reproduced at the end of Dahl's chapters). Despite the charming elements of his joking, outspoken personality, Centipede's outlandish personality sometimes gets him into trouble.

Despite her scary appearance (and her status as an animal that many humans misunderstand), Miss Spider is incredibly kind and acts as a caring mother figure towards James. She is responsible for spinning the hammock-like beds for all of the passengers of the peach, and her skillful spinning is very useful later in the novel. In particular, Miss Spider's skills are essential in the peach's escape from danger; at sea, she spins the strands of rope that James needs for his daring seagull scheme.

However, Miss Spider has suffered a few family casualties. During the novel, Miss Spider explains that her father was killed by Aunt Sponge, who sent him down a bathtub drain to his death. Fortunately, Miss Spider lives happily ever after at the end of the novel. Together with her comrade Silkworm, she sets up a factory that manufactures ropes for tightrope walkers.
