Once upon a time, the pigs looked similar to the dogs and ate grass like the goats. They were very arrogant and their grunt could be heard miles around. The animals found it difficult to sleep at night due to the grunts. A piglet named Onk was very fond of laying a bet with the other animals and often won the wager but he was very silly. The other animals wanted to teach the pigs a lesson for disturbing their peaceful night came up with a plan.
