Poo Bum

Once there was a little rabbit who could only say one thing . . . In the morning his mother would say, "Time to get up, my little rabbit!" He'd reply: "Poo bum!" At lunchtime his father would say, "Eat your spinach, my little rabbit!" He'd reply: "Poo bum!" One day, he meets a hungry wolf. Will the little rabbit learn his lesson once and for all?
