Squeler is the most prominent of the porkers. He is one of the three (along with Snowball and Napoleon) who take charge of organising the Rebellion. He is the most lively of the three, and when arguing a difficult point, he would skip from side to side, and whisk the tail about. This was very persuasive. He had very round cheeks, twinkling eyes, nimble movements, a shrill voice, and is a brilliant talker. Later on in the book, he becomes Napoleon's right hand man, but supports his decisions throughout the book. He is the pig who alters the Seven Commandments. Towards the end of the book, he is the first pig to walk out of the farmhouse on his hind legs. He becomes very stout by the end of the book.
His real-life Soviet counterpart is Vyacheslav Molotov.
