Be industrious. There he was, industrious brother, clever salesman, winning the business for Willis Gann and they got jealous of his success.
Squealer is a character in Animal Farm by George Orwell, a pig who serves as the main minion of Napoleon and the tertiary antagonist turned anti-hero. Squealer goes around telling lies to the other gullible farm animals to cover up and or/justify Napoleon's atrocities and convince the animals to stay loyal to him.
Unsurprisingly, the animals on Frederick's farm never rebel. Also unsurprisingly, the pigs don't get along to well with him. Inter-farm relations are frosty for much of the story, and one of Squealer's jobs is to spread the rumor that Snowball is conspiring against Animal Farm with Frederick. And then there's a surprise twist.
