Small Pig likes to eat, sleep, and run. But most of all he likes nice, soft mud. Everything is fine on the farm until the farmer's wife cleans up everything — even Small Pig's mud puddle. Then he runs away to the city — sure that since the city is so dirty he will find a puddle there. But, once there, the puddle he thought was mud is not mud at all! And now this small pig has one BIG problem.
