'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.

A wonderfully fun, imaginative story with a reassuring, heart-warming conclusion that every grandchild (and grandmother!) will love!
