Bernard the Backward-flying Pig in 'Chicken Jail'

Bernard is a clever, funny, friendly, backward-flying pig - but, even with rear-view mirrors, flying backwards is tricky! Bernard always has bumps on his rump! At Friendship Farm, Mabel is Bernard's best friend, number one chicken and co-pilot. Bernard is great at working out plans to get himself out of trouble. Bernard makes up songs to help him think, plan and to keep him going when things get tough. - and things get tough when Mabel lands herself in Chicken Jail. How did that happen? And what can Bernard do to get her out?
