He serves as second-in-command to Napoleon, the pigs' leader, and is the farm's minister of propaganda.

He is briefly outraged by Boxer's death, but becomes ever more cynical when Squealer again convinces the denizens of the Farm that Boxer was only taken to a hospital.
To prevent the animals from suspecting them, Squealer preys on the animals' confusion and alters the Commandments from time to time as the need arises.
Squealer falls off a ladder while trying to change one of the commandments in the night.
