"MR JONES WILL COME BACK FOR US BACK IF WE GET SICK"!
All the animals have a reunion on the barn because they are all confused by what happened to the apples and the milk.
"It's okay that the pigs keep them so that Mr Jones doesn't come back!"
The Pigs explain to the rest of the farm what happened to the apples and the milk and they said they had took them because the pigs needed them the most to stay healthy.
"Which where the 7 Commandments?"
The pigs spread fear to the rest of the animals by telling them that if they (the pigs) got sick, Mr. Jones would come back to the farm and mistreat them again. Therefore they needed to keep all of the apples and the milk to themselves.
"Four Legs Good, Two Legs Bad!" "Four Legs Good, Two Legs Bad!"
All of the animals get scared so they decide to allow the pigs to keep the apples and milk fearing that Mr Jones would come back if they didn't.
The animals had trouble learning all of the commandments so, they reduce it to only "Four Legs Good, Two Legs Bad".
The sheep really seem to like the new and reduced commandment so they keep repeating it many times while they keep working.
