By the next day, Napoleon was back to work, healthy as usual.
One night at around 12 o'clock, the farm animals heard a loud sound coming from outside the barn. The farm animals rushed outside and see Squealer, as he had fallen off a ladder in front of the seven commandments. They quickly rushed to his aid and brought him back to the farmhouse.
The fifth commandment was changed from 'No animals shall drink alcohol' to 'No animal shall drink alcohol to excess'. I see what these pigs are doing... they're no better than the humans.
The next morning, the farm animals couldn't figure out what happened last night. However, the old horse Benjamin understood what had happened, but didn't say anything in fear of the pigs.
