Is Your Grandmother A Goanna?'Have you seen my grandmother?' asked the little boy. 'There are only goannas here,' replied the station master. 'Is your grandmother a goanna?' One day a little boy sets out to visit his grandmother. But each station he comes to is full of a different sort of animal, and his grandmother is not a gorilla, or an elephant, or a walrus or a goanna! So the train steams on Chuffa Chuffa, Chuffa, Chuffa until finally, on the very last station, there she is.
