'Mrs Grey is very worried. Ever since Big Red, the leader of all the kangaroos in the world, helped Keith to find his hop - he just can’t STOP hopping! Big Red again tries several ingenious ways to help but, in the end, sends Keith back to the hop-spital to see Dr Leapyear, the hop-tician. This time the doctor decides to try hop-nosis. But will it work? Will Keith EVER be able to stop hopping? '
