with Johnny Morris
What makes a glow worm glow? JOHNNY reveals what makes certain animals light up at night. What bird can fly backwards? The humming-bird -candidate for the world's most colourful bird. As well as humming-birds in the studio, Johnny's guests include a pair of Stanley cranes that keep undoing his shoelaces.
And Keeper Morris has some monster animals to look after - everything from a dinosaur to a blue whale - all in the Natural History Museum.
