In Animal Farm how is the character Squealer sneaky?

Squealer represents the media. Squealer continually changes his story in order to get the animals to believe what Napoleon wants them to believe. Every time the animals think that things are not right, Squealer comes to tell them a new story that explains how everything is ok. For example, when the animals see the pigs breaking the "No Animal Shall Sleep in a Bed" commandment, Squealer alters the story slightly to "No Animal Shall Sleep in a bed with sheets" making the pigs in compliance with the rules of Animal Farm.
