In his short-lived time as a leader, Snowball actively works to change Animal Farm, and although not all of his ideas work very efficiently, he is shown to have genuinely good intentions. Despite his altruism, however, he has his faults, such as when he, like the other pigs, hoards the milk and windfallen apples. Like Trotsky, Snowball is exiled after Napoleon seizes power by force, modeled after Joseph Stalin. After Snowball is exiled, he is used by Napoleon as a political scapegoat and is blamed for various problems on the farm. For example, he is blamed for allegedly mixing weed seeds into the wheat seeds under the cover of night to explain the growth of weeds in the farm's crops. He is also blamed for the destruction of the windmill the animals had created. Other animals make false confessions (an idea Orwell expands in 1984) saying they helped him in his "nightly visits," or he came to them in a dream telling them to do bad deeds and they are executed brutally in public. (The killing is likely a parallel to the Great Purge started by Stalin in 1936 when he tried and executed many of his political adversaries using forced false confessions.) There is never a sure confirmation that Snowball is alive or dead as he was never seen again after his exile.
He returns to bring Capitalism to the Manor Farm in John Reed's controversial 9/11 follow up Snowball's Chance, where he brings capitalism to the Manor Farm. Like Napoleons puppies, he had a team of goats that helped him out. The George Orwell estate objected to the publication of the work.
Snowball also writes the first version of the Seven Commandments. These are later altered by Squealer under the orders of Napoleon to accommodate the treacherous actions of the pigs. For example, the commandment stating "No animal shall drink alcohol" is changed to "No animal shall drink alcohol to excess."
