"The moods of the octopus are revealed in her changing hues: she will turn red, black, purple, or yellow, depending on the area of pigment she contracts. Experiments have shown that she remembers things, recognizes things, and can adapt to society. She is offended by foul-smelling eggs and will throw them back at you violently, turning white with anger."
