What episode causes squealer to use trickery?

In George Orwell's "Animal Farm," Squealer uses trickery in several instances, but one notable episode is when he manipulates the truth about the pigs' consumption of the farm's resources. After the pigs begin to drink alcohol and engage in activities that contradict the original commandments of Animalism, Squealer uses Propaganda to convince the other animals that these actions are for their benefit and that the farm is better off under the pigs’ leadership. He twists the narrative to maintain control and suppress dissent.
