Snowball

Snowball's escape due to enormous dogs' attack represent the exile of Trotsky in Russia. Napoleon and Snowball's rivalry resemble rivalry of Stalin and Trotsky. Stalin's opposing theory of Trotsky's Permanent Revolution made Trotsky unpopular among Party members. "Stalin made sure that Trotsky was always voted down in the Politburo."(Pg.7 of Stalin and the Soviet Union) Later, Trotsky was expelled from Russia like Snowball escaped from the Animal Farm and the attack from Napoleon's dogs. ㅡSung-Woo Choㅡ
