There's a new boy in George and Cathy's neighborhood of Sydney; his name is Martin, and he claims to be a visitor from outer space. Of course, no one took him seriously at first, but he does have an odd way of staring at you; then there's his habit of squeezing into very small places, his occasional green glow, and of course, the way he bounces. And now the Children's Protective Agency has taken an interest, and it seems to be up to Cathy and George to protect their odd new friend from the dangerous curiosity of the adult world.
